The NaH-mediated N-methylbenzimidazole formation starting from carbonitriles and N-methyl-1,2-phenylenediamine is reported to be a procedure compatible with acid-labile acetal protective groups within the starting materials. Products were further converted in Suzuki, Sonogashira, Heck and Buchwald-Hartwig reactions.
报道了以氰化物和N-甲基-1,2-苯二胺为起始材料,利用NaH介导合成N-甲基苯并咪唑的方法。该程序与起始材料中的易受酸影响的缩醛保护基相容。产品进一步转化为铃木反应、Sonogashira反应、Heck反应和Buchwald-Hartwig反应。
