摘要

A salt of the compound (3'R,4'S)-6-[2-(2,6-Dichloro-4-methyl-phenoxy)-ethoxy]-1',2',3',4',5',6'-hexahydro-[3,4']bipyridinyl-3'-carboxylic acid [2-chloro-5-(2-methoxy-ethyl)-benzyl]-cyclopropyl-amide selected from the group consisting of monoacetate salt and bis-D-tartrate salt. In one embodiment of the invention, the salt is (3',4'S)-6-[2-(2,6-Dichloro-4-methyl-phenoxy)-ethoxy]-1',2',3',4',5',6'-hexahydro-[3,4']bipyridinyl-3'-carboxylic acid [2-chloro-5-(2-methoxy-ethyl)-benzyl]-cyclopropyl-amide monoacetate. In one embodiment of the invention, the salt is (3'R, 4'S)-6-[2-(2,6-Dichloro-4-methyl-phenoxy)-ethoxy]-1',2',3',4',5',6'-hexahydro-[3,4']bipyridinyl-3'-carboxylic acid [2-chloro-5-(2-methoxy-ethyl)-benzyl]-cyclopropyl-amide bis-D-tartrate. The invention also describes a asymmetric synthesis of (3'R, 4'S)-6-[2-(2,6-Dichloro-4-methyl-phenoxy)-ethoxy]-1',2',3',4',5',6'-hexahydro-[3,4']bipyridinyl-3'-carboxylic acid [2-chloro-5-(2-methoxy-ethyl)-benzyl]-cyclopropyl-amide as a monoacetate salt or as a bis-D-tartrate salt.
