Improved Process for Preparation of Gemfibrozil, an Antihypolipidemic
摘要:
An improved process for the preparation of gemfibrozil, an antihypolipodimic drug substance, with an overall yield of 80% and similar to 99.9% purity (including three chemical reactions) is reported. Formation and control of possible impurities are also described. Finally, gemfibrozil is isolated from water without any additional solvent purification.
