20090124577 | Intermediate Compounds for the Preparation of an Angiotensin II Receptor Antagonist - It comprises new substituted 4-valinylmethylphenyl boronic acids of formula (II) and their derivatives and also its preparation process. It also comprises a preparation process of Valsartan (I) from such intermediates. The process comprises the reaction of the new 4-valinylmethylphenyl boronic compounds with a (halophenyl)tetrazole compound which proceeds with high yields. The process is particularly advantageous in its practical industrial realization because it avoids the use of azide derivatives and also the use of expensive biphenyl intermediates. | 05-14-2009 |
20110104765 | STEREOSELECTIVE SYNTHESIS OF METYROSINE - Provided herein are compositions including diastereomers in substantially diastereomerically pure form and enantiomers in substantially enantiomerically pure form, and processes for preparing them and converting them to metyrosine. | 05-05-2011 |
20140350284 | STEREOSELECTIVE SYNTHESIS OF METYROSINE - Provided herein are compositions including diastereomers in substantially diastereomerically pure form and enantiomers in substantially enantiomerically pure form, and processes for preparing them and converting them to metyrosine. | 11-27-2014 |

20110082301 | Preparation of Delmopinol - It comprises a process for the production of delmopinol or a pharmaceutically acceptable salt and/or a solvate thereof, by subjecting the compound of formula (II) where R1 and R2 are the same or different, independently selected from the group consisting of H, (C1-C6) alkyl or, alternatively, R1 and R2 form, together with the carbon atom to which they are attached, a (C5-C6) cycloalkyl radical; and R3 is a radical selected from the group consisting of CF3, (C1-C4) alkyl, phenyl, and phenyl mono- or disubstituted by a radical selected from the group consisting of (C1-C4)-alkyl, halogen and nitro to a deprotection and cyclisation reaction. The process is useful to prepare delmopinol or its salts on an industrial scale. The compound of formula (II) is new and also forms part of the present invention, as well as its preparation process and other new intermediates of said preparation process. | 04-07-2011 |

20080300411 | Process for the Preparation of the (S)-Enantiomer of Omeprazole - A process for the preparation of (S)-omeprazole from racemic omeprazole via the formation of an inclusion complex with (S)-1,1,2-triphenyl-1,2-ethanediol. (S)-Omeprazole is recovered in a substantially optically pure form either in neutral form or as a pharmaceutically acceptable salt or as its solvates including hydrates. The (S)-omeprazole 2[(S)-1,1,2-triphenyl-1,2-ethanediol] inclusion complex is new. This resolution process proceeds with high yields and high optical purity. | 12-04-2008 |
20090036677 | Preparation of Delmopinol - It comprises a preparation process of delmopinol or a pharmaceutically acceptable salt and/or a solvate thereof, by submitting the compound of formula (II) where R | 02-05-2009 |

20090137841 | PROCESS FOR THE PREPARATION OF AROMATIC DERIVATIVES OF 1-ADAMANTANE - Process for the obtaining of 1-adamantane (tricycle[3.3.1.1 (3,7)]decane) derivatives, or of a pharmaceutically acceptable salt thereof, based on a carboxylation reaction, via metallation, of a precursor compound with an adequate leaving group. It also comprises the preparation of the precursor compound by means of a selective coupling of the corresponding boron, magnesium or zinc derivative with the corresponding disubstitute aromatic derivative. It is especially useful for the obtaining of Adapalene at industrial scale with good yield and high purity. | 05-28-2009 |
20100010265 | PROCESS FOR THE PREPARATION OF AROMATIC DERIVATIVES OF 1-ADAMANTANE - Process for the obtaining of 1-adamantane (tricycle[3.3.1.1 (3,7)]decane) derivatives, or of a pharmaceutically acceptable salt thereof, based on a carboxylation reaction, via metallation, of a precursor compound with an adequate leaving group. It also comprises the preparation of the precursor compound by means of a selective coupling of the corresponding boron, magnesium or zinc derivative with the corresponding disubstitute aromatic derivative. It is especially useful for the obtaining of Adapalene at industrial scale with good yield and high purity. | 01-14-2010 |
20110040115 | INTERMEDIATES AND PROCESS FOR THE PREPARATION OF AROMATIC DERIVATIVES OF 1-ADAMANTANE - Process for the preparation of aromatic derivatives of 1-adamantane (tricyclo[3.3.1.1 (3,7)]decane), or an acceptable pharmaceutical salt thereof, based on a hydrolysis reaction of a precursor cyano compound. It also comprises different processes for obtaining the cyano compound. It is especially useful for obtaining Adapalene on an industrial scale in high yield and purity. It also comprises new intermediates useful in said preparation process. | 02-17-2011 |
20120283434 | PROCESS FOR THE PREPARATION OF RIVAROXABAN AND INTERMEDIATES THEREOF - A process for the preparation of rivaroxaban, or a pharmaceutically acceptable salt thereof, or a solvate thereof, including a hydrate, comprising submitting an amine compound of formula (III) wherein R | 11-08-2012 |
