A method for preparing optionally substituted N-[1-(S)-carbalkoxy-3-phenylpropyl]-S-alanyl-2S,3aR,7aS-octahydroindole-2-carboxylic acid} and pharmaceutically acceptable salts thereof, wherein a racemic mixture of optionally substituted trans-octahydroindole-2-carboxylic acid is reacted with the N-carboxyanhydride of N-[1-(S)-alkoxycarbonyl-3-phenylpropyl]-L-alanine}, which is optionally substituted on the phenyl ring, in a suitable inert solvent, and subsequently the resulting optionally substituted N-[1-S-carbalkoxy-3-phenylpropyl]-S-alanyl-2S,3aR,7aS-octahydroindole-2-carboxylic acid}, preferably trandolapril, is isolated, and polymorphic forms A and B of trandolapril.
一种制备可选取代的N-[1-(S)-碳酰基氧基-3-苯基丙基]-S-丙氨酰-2S,3aR,7aS-八氢吲哚-2-羧酸}及其药学上可接受的盐的方法,其中可选取代的反式八氢吲哚-2-羧酸的混合物与可选取代的苯环上的N-[1-(S)-烷氧羰基-3-苯基丙基]-L-丙氨酸}的N-羧酸酐在适当的惰性溶剂中反应,随后分离得到可选取代的N-[1-(S)-碳酰基氧基-3-苯基丙基]-S-丙氨酰-2S,3aR,7aS-八氢吲哚-2-羧酸},优选为曲唑普利(trandolapril),以及曲唑普利的多形体A和B。
