| 20110015189 | METHODS OF MAKING EFAVIRENZ AND INTERMEDIATES THEREOF - The present invention provides a process for the preparation of Efavirenz. A compound of Formula 1 may be prepared by a process comprising cyclizing, in the presence of a first base, a compound of Formula 5 with a haloformate of Formula 6. Other processes are also provided as well as novel compounds prepared by and used in such processes. | 01-20-2011 |
| 20100324298 | Novel Process for the Preparation of Esomeprazole and Salts Thereof - A novel process for the preparation of omeprazole and its enantiomers, such as esomeprazole, as well as the preparation of related 2-(2-pyridinylmethyl-sulphinyl)-1H-benzimidazoles, including pantoprazole, lansoprazole and rabeprazole, as recemates or single enantiomers, and their alkali or alkaline salts has been developed. The novel process involves the surprising discovery that protection of the free-base benzimidazole sulfoxide (e.g. omeprazole or esomeprazole), by reaction with an alkyl, aryl or aralkyl chloroformate following oxidation of the corresponding sulfide, eliminates the need for its direct isolation. Subsequent removal of the protecting group with a solution of alkali or alkaline earth alkoxide in a C1-C4 alcohol directly provides the corresponding salt. By eliminating the need to handle the free-base benzimidazole sulfoxide, this advantageous procedure provides increased chemical yields over processes described in the art. | 12-23-2010 |
