专利号:WO-9847870-A1 优先权日:1997-04-24 标 题:Process for the synthesis of 4-[6-(hexylcarbamoyloxy) hexylcarbamoyloxy]-piperidine-1- carboxylic acid 4-phenoxyphenyl ester 发明人:JIRKOVSKY IVO 权利人:AMERICAN HOME PROD 摘要:This invention is concerned with a new and improved process for the large scale production of 4-[6-(hexylcarbamoyloxy)hexylcarbamoyloxy]-piperidine-1-carboxylic acid 4-phenoxyphenyl ester, disclosed in European Patent Application 0 635 501 A1, published January 25, 1995, a compound that inhibits cholesterol ester hydrolase (CEH) and acylcoenzyme A cholesterol acyltransferase (ACAT). In the invention process, 1-benzyl-4-hydroxypiperidine or 1-methyl-4-hydroxypiperidine is reacted with a carbonylating reagent such as carbonyldiimidazole (CDI) and 6-aminohexanol forming the intermediate 1-benzyl (or methyl)-4-(6-hydroxyhexylcarbamoyloxy)piperidine. Reaction of this intermediate with CDI and hexylamine gives the corresponding 1-benzyl (or methyl)-4-[6-(hexylcarbamoyloxy)-hexylcarbymoyloxy]piperidine. The N-benzyl or methyl group is concomitantly removed and replaced with the 4-phenoxyphenyloxycarbonyl group using 4-phenoxyphenyl chloroformate. The process can be carried out from starting material to final product without isolation of intermediates, without changing the solvent, and the yield and purity of the final product are still more than satisfactory. This modification of the present process is clearly less labor and time intensive than the synthetic route presented in EP 0 635 501 A1.
