The present application provides a process for the preparation of α-carboxamide pyrrolidine derivatives of formula (I), wherein R1 and R2 are independently hydrogen, C1-6alkyl or C3-6cycloalkylC1-6alkyl; or such R1 and R2, together with the nitrogen to which they are attached, may form an unsubstituted 3-, 4-, 5- or 6-membered saturated ring; X is carbon or nitrogen; n is 0, 1 or 2, wherein when present each R5 is independently selected from the list consisting of C1-3alkyl, halogen, cyano, haloC1-3alkyl, hydroxy, C1-3alkoxy and C1-3haloalkoxy; either R6 or R7 is -O-R8, -OCHR9R8, -NCH2R8 or -(CH2)2R8 wherein the other R6 or R7 is hydrogen or R5; and wherein R8 is a phenyl ring or wherein the phenyl ring is optionally substituted by one or more groups independently selected from the list consisting of C1-3alkyl, halogen, cyano, haloC1-3alkyl, hydroxy, C1-3alkoxy and C1-3haloalkoxy; and R9 is hydrogen or C1-3alkyl.
本申请提供了一种制备式(I)的α-羧酰胺吡咯烷衍生物的过程,其中R1和R2分别是氢、C1-6烷基或C3-6环烷基C1-6烷基;或者这样的R1和R2,连同它们附着的氮,可以形成未取代的3、4、5或6-成员饱和环;X是碳或氮;n为0、1或2,当存在时,每个R5独立地从C1-3烷基、卤素、氰基、卤代C1-3烷基、羟基、C1-3烷氧基和C1-3卤代烷氧基的列表中选择;R6或R7是-O-R8、-OCHR9R8、-NCH2R8或-(CH2)2R8,另一个R6或R7是氢或R5;其中R8是苯环或苯环可以选择地由一个或多个独立选择的C1-3烷基、卤素、氰基、卤代C1-3烷基、羟基、C1-3烷氧基和C1-3卤代烷氧基基团取代;R9是氢或C1-3烷基。
