Gerard Coquerel, Notre Dame De Bondeville FR
| Patent application number | Description | Published |
|---|---|---|
| 20090124811 | Method for resolving omeprazole salts - The present invention relates to the resolution by preferential crystallization of potassium salts of racemic omeprazole which is a solvate of ethanol and/or of ethylene glycol, which consists in converting the omeprazole to the potassium salt in the form of a solvate or of a mixture of these solvates in the presence of an excess of inorganic base which is a source of potassium, the said potassium salts existing in the form of conglomerates, and in then resolving the said conglomerates, independently or simultaneously, by preferential crystallization in order to separate the two (S) and (R) enantiomers of these potassium salts of omeprazole. | 05-14-2009 |

| 20090048449 | RIMONABANT MONOHYDRATE, PROCESS FOR THE PREPARATION THEREOF AND PHARMACEUTICAL COMPOSITIONS CONTAINING SAME - The present invention relates to rimonabant monohydrate, to the process for preparing it and to the pharmaceutical compositions containing it. | 02-19-2009 |
Gerard Coquerel, Mont Saint Aignan FR
| Patent application number | Description | Published |
|---|---|---|
| 20110269798 | PRECURSOR PHASE AND USE THEREOF FOR PREPARING THE MAGNESIUM TETRAHYDRATE SALT OF AN OMEPRAZOLE ENANTIOMER - A precursor phase of the magnesium tetrahydrate salt of an omeprazole enantiomer, and also processes for preparing it and its use for the preparation of the magnesium tetrahydrate salt are described. Crystals of the magnesium tetrahydrate salt thus obtained, and their uses, especially in the synthesis of the dihydrate form A of the magnesium salt of the enantiomer or as medicament are also disclosed. | 11-03-2011 |
