PROCESS FOR PREPARATION OF PHARMACEUTICAL INTERMEDIATES

摘要

The present invention provides an improved process for the preparation of (+)-7-[4-(4-fluorophenyl)-6-isopropyl-2-(methanesulfonyl-methyl-amino)-pyrimidin-5-yl]-(3R,5S)- dihydroxy-hept-6-enoic acid and sodium salt thereof. A further subject of the present invention is high purity (+)-7-[4-(4-fluorophenyl)-6-isopropyl-2-(methanesulfonyl-methyl-amino)-pyrimidin-5-yl]-(3R,5S)-dihydroxy-hept-6-enoic acid sodium salt and process for the preparation thereof. The compound of the general Formula (I) and sodium salt thereof are valuable pharmaceutical intermediates during the production of high purity pharmaceutically active ingredients suitable for the regulation of lipid metabolism.
