This invention concerns a process for preparing 2-amino-1,5(6)-substituted-benzimidazole compounds by reacting a 1-unsubstituted-2-amino-5(6)-substituted benzimidazole compound with a sulfonyl chloride or a haloalkyl isothiocyanate in the presence of an acid acceptor base, water, and a water-miscible nonhydroxylic solvent.
本发明涉及一种制备 2-氨基-1,5(6)-取代的苯并咪唑化合物的工艺,其方法是在酸受体碱、水和水混溶的非羟基溶剂存在下,使 1-未取代的 2-氨基-5(6)-取代的苯并咪唑化合物与磺酰氯或卤代烷基异硫氰酸酯反应。
