| 20090047354 | PROCESS FOR THE PREPARATION OF 5-(2-(4-(1,2-BENZISOTHIAZOL-3-YL)-1-PIPERAZINYL) ETHYL)-6-CHLORO-1, 3-DIHYDRO-2H-INDOL-2-ONE HYDROCHLORIDE (ZIPRASIDONE HYDROCHLORIDE) AND ITS INTERMEDIATE - The present invention relates to improved processes for the preparation of 5-(2-(4-(1,2-benzisothiazol-3-yl)-1-piperazinyl)ethyl)-6-chloro-1,3-dihydro-2H-indol-2-one and its hydrochloride, which is known as Ziprasidone hydrochloride of Formula (I) and 5-(2-Chloro acetyl)-6-chloro oxindole of Formula (IV), which is an intermediate for the preparation of 5-(2-chloro ethyl)-6-chloro oxindole of Formula (V). Ziprasidone hydrochloride of Formula (I) of the present invention is depicted by the following structure. | 02-19-2009 |
| 20090137605 | POLYMORPHIC FORMS OF ZIPRASIDONEAND ITS HYDROCHLORIDE SALT AND PROCESS FOR PREPARATION THEREOF - The present invention is related to crystalline forms of ziprasidone and its hydrochloride salt and an amorphous form of ziprasidone hydrochloride and the process for the preparation thereof. The crystalline forms and amorphous form of the invention are suitable for pharmaceutical purposes in the treatment of psychosis. The processes of the invention are simple, non-hazardous and commercially suitable. | 05-28-2009 |
| 20100016606 | PREPARATION OF AMORPHOUS HYDROUS ESOMEPRAZOLE MAGNESIUM - A hydrate of esomeprazole magnesium in the form of an amorphous solid is provided. Methods of preparation and use of, as well as formulation containing the hydrate of esomeprazole magnesium in the form of an amorphous solid are also provided. | 01-21-2010 |
| 20100056783 | Novel Process for the Preparation of Statins and their Pharmaceutically Acceptable Salts thereof - Novel process for the preparation of statins and their pharmaceutically acceptable salts thereof represented by the general formula-(1) through novel intermediate compounds of general formula-(4). | 03-04-2010 |
| 20100179345 | NOVEL PROCESS FOR THE PREPARATION OF PREGABALIN - The present invention encompasses novel intermediates of pregabalin, namely 3-cyano-5-methyl hexanamide (28) and 3-(amino methyl)-5 methyl hexanamide (29), and processes for their preparation. The invention also encompasses a process for converting the novel pregabalin intermediates into pregabalin, Formula (I): The present invention further provides a cost effective method for the synthesis of (S)-pregabalin, which involves the recovery of mandelic acid and tartaric acid used in the resolution process and recycling them, increasing the yields of the final product formed, which substantially reduced the cost of the production. | 07-15-2010 |
