A process for preparation of crystalline perindopril erbumine of formula (II) which exhibits the X-ray (powder) diffraction pattern like that shown in the figure. The process comprises reacting a solution of perindopril of formula (I), in a solvent selected from N, N-dimethylformamide or dimethyl acetals of lower aliphatic aldehydes and ketones with tertiary butylamine and crystallization of the erbumine salt thus obtained by heating the reaction mixture to reflux, filtering hot, cooling gradually to 20 ºC to 30 ºC, and further cooling to 0º C to 15 ºC for 30 minutes to 1 hour and finally filtering off and drying the crystals.
一种制备结晶盐酸培哌普利的方法,其化学式为(II),表现出X射线(粉末)衍射图谱,类似于所示图中的图谱。该方法包括将化学式(I)的培哌普利溶液在从N,N-二甲基甲酰胺或低碳链脂肪醛和酮的二甲基缩醛中选择的溶剂中与叔丁胺反应,并通过加热反应混合物至沸腾,热过滤,逐渐冷却至20°C至30°C,进一步冷却至0°C至15°C 30分钟至1小时,最后过滤和干燥晶体来结晶盐酸培哌普利。
