Abstract

本发明涉及一种合成式(I)培哚普利及其药学上可接受的盐的方法。

Description

合成培哚普利及其药学上可接受的盐的方法
本发明涉及一种工业上合成式(I)的培哚普利及其药学上可接受的盐的方法:
Figure C0180737200051
培哚普利及其药学上可接受的盐,更详细地讲,它的叔丁基胺盐,具有有价值的药理学性质。
它们的主要性能在于对转化血管紧张肽I(或激肽酶II)的酶的抑制作用,它一方面能防止十肽血管紧张肽I转化成八肽菌素血管紧张肽II(血管收缩剂),另一方面能防止缓激肽(血管舒张剂)降解成非活性肽。这两个作用归因于培哚普利在心血管疾病、尤其是动脉高血压和心功能不全方面的有利效果。
EP 0 049 658描述了培哚普利、其制备方法和其治疗用途。
关于这种化合物的药学意义,重要的是能通过一种有效的工业合成方法获得该化合物,该方法易于在工业规模应用,能得到良好的培哚普利产率,尤其是具有优异的纯度。
EP 0 308 341描述了通过将(2S,3aS,7aS)-八氢吲哚-2-羧酸苄基酯与N-[(S)-1-羧丁基-(S)-丙氨酸乙基酯偶合,然后通过催化氢化脱去杂环上的羧基来工业合成培哚普利的方法。
该方法的优势在于:以已经描述的工业合成用的原料为起始原料,得到的培哚普利的产率良好。
然而,通过这种方法得到的培哚普利的纯度不令人满意,有必要进行提纯步骤,以获得具有可用作药物活性成分的质量的培哚普利。
实际上,在这个专利说明书描述的情况下,得到的培哚普利被显著量的式(II)和式(III)杂质污染:
Figure C0180737200061
申请人现在开发出一种新的工业合成培哚普利的方法,该方法生产的培哚普利的纯度与其用作药物活性成分的用途相容,式(II)和式(III)杂质的水平分别低于0.2%和0.1%。
更详细地讲,本发明涉及一种工业合成培哚普利的方法,其特征在于将式(IV)的苄基酯:
Figure C0180737200062
其中Bn代表苄基,
与式(V)化合物:
在乙酸乙酯中,在0.4-0.6摩尔1-羟基苯并三唑/摩尔式(IV)化合物的存在下以及1-1.2摩尔二环己基碳二亚胺/摩尔式(IV)化合物的存在下,在没有三乙胺存在下或三乙胺的量少于或等于1摩尔/摩尔式(IV)化合物,优选少于或等于0.25摩尔/摩尔式(IV)化合物,在20-77℃下反应,
分离后得到式(VI)化合物:
Figure C0180737200072
其中Bn代表苄基,
通过催化氢化使其杂环上的羧基脱去保护,得到式(I)的培哚普利,
如果需要,将它转化成药学上可接受的盐,如叔丁基胺盐。
本方法具有特别的意义,理由如下:
在式(IV)苄基酯的碱性介质中与式(V)化合物的偶合已在EP 0 308341中描述过,但是在所述条件(使用3摩尔式(V)化合物,3摩尔三乙胺,3.8摩尔1-羟基苯并三唑以及2.9摩尔二环己基碳二亚胺/摩尔式(IV)化合物)下,生成了大量的副产物。
尤其,得到的式(VI)化合物含有显著量(5-15%)的式(VII)和式(VIII)杂质,当进行脱苄基化时,得到式(II)和式(III)的杂质
Figure C0180737200081
申请人意外地发现,三乙胺在偶合步骤中的减少或甚至忽略不计使得有可能将式(VI)化合物中的式(VII)和式(VIII)杂质的含量限制在低于1.5%。
-这样得到的式(VI)化合物的催化氢化使得到的培哚普利的纯度更高,特别是式(II)和式(III)杂质的含量分别低于0.2%和0.1%。
-除此以外,在偶合步骤中,式(V)化合物、1-羟基苯并三唑和二环己基碳二亚胺的量的减少使得到的式(VI)化合物的产率与用大量试剂得到的产率一样好,因此使该方法在工业规模上更有利。
下列实施例说明本发明,但绝不限制本发明。
实施例1:(2S,3aS,7aS)-1-{(2S)-2-[(1S)-1-(乙氧基羰基)-丁基氨基]-丙酰基}-八氢-1H-吲哚-2-甲酸苄基酯:
在搅拌下,将1kg(2S,3aS,7aS)-八氢吲哚-2-羧酸苄基酯对甲苯磺酸酯,0.06kg三乙胺,4.6升乙酸乙酯加入反应器,然后在室温下搅拌10分钟以后,再加入0.52kg N-[(S)-乙氧基羰基-1-丁基]-(S)-丙氨酸,0.15kg 1-羟基苯并三唑和0.5kg二环己基碳二亚胺。然后将非均相混合物加热到30℃,在此温度下充分搅拌3小时,随后冷却至0℃,过滤。
然后洗涤滤液,随后蒸发至干,得到产率为92%的预期产物。
实施例2:(2S,3aS,7aS)-1-{(2S)-2-[(1S)-1-(乙氧基羰基)-丁基氨基]-丙酰基}-八氢-1H-吲哚-2-甲酸:
将前步得到的残渣(1kg)溶解在1升的甲基环己烷中,将溶液转移到氢化器中;然后加入0.13kg悬浮在0.4升甲基环己烷中的5%的披钯碳,接着加入3.2升水。
然后将混合物在15-30℃下,在0.5巴压力下氢化,直到吸收了理论量的氢。
过滤除去催化剂后,用甲基环己烷洗涤滤液的水相,然后冻干得到产率为94%的预期产物。
实施例3:(2S,3aS,7aS)-1-{(2S)-2-[(1S)-1-(乙氧基羰基)-丁基氨基]-丙酰基}-八氢-1H-吲哚-2-甲酸叔丁基胺盐:
将在前步中得到的冻干物(1kg)溶解在14升的乙酸乙酯中;然后加入0.2kg叔丁基胺和2升乙酸乙酯。然后将得到的悬浮液在回流下加热直到完全溶解,然后趁热过滤得到的溶液,在搅拌下冷却至15-20℃。
然后滤除得到的沉淀,用乙酸乙酯使之再变成糊状,干燥,然后研磨,得到产率为95%的预期产物。
