readily available p-substituted-benzylamines a series of ethyl 2-alkylthio-1-substituted-ben-zylpyrrolo[2,3-d]imidazole-5-carboxylates was prepared. In addition, starting from 2-alkyl-4(or 5)-formylimidazoles and methyl 4′-bromomethylbiphenyl-2-carboxylate a series of methyl substituted-pyrrolo[2,3-d]imidazole-5-carboxylates and methyl substituted-pyrrolo[3,2-d]imidazole-5-carboxylates was prepared.
从容易获得的对位取代的苄基胺开始,制备了一系列的2-烷基硫基-1-取代的苯-苄基吡咯并[2,3 - d ]咪唑-5-羧酸乙酯。另外,从2-烷基-4(或5)-甲酰咪唑和甲基4'-溴甲基联苯-2-羧酸酯开始,一系列甲基取代的吡咯并[2,3 - d ]咪唑-5-羧酸酯和甲基取代的吡咯并制备[3,2-d]咪唑-5-羧酸盐。
