A process for preparing, on an industrial scale, 4-halo-5-(hydroxymethyl) imidazole compounds that are useful as intermediates for medicines. A 4-chloro-5-(hydroxymethyl) imidazole compound, a 4-bromo-5-(hydroxymethyl) imidazole compound or a like compound is synthesized by reacting a 4,5-bis(hydroxymethyl) imidazole compound with a halogenating agent such as an N-chlorosuccinimide, an N-bromosuccinimide, a chlorinated isocyanuric acid compound or the like compound.
一种用于在工业规模下制备有用于药物中间体的4-卤代-5-(羟甲基)咪唑化合物的方法。通过将4,5-双(羟甲基)咪唑化合物与卤化剂(如N-氯琥珀酰亚胺、N-溴琥珀酰亚胺、氯化异氰尿酸化合物或类似化合物)反应合成4-氯-5-(羟甲基)咪唑化合物、4-溴-5-(羟甲基)咪唑化合物或类似化合物。
