A four-step synthesis of the PARP inhibitor 2-(4-trifluoromethylphenyl)benzimidazole-4-carboxamide (1, NU1077) is presented. Condensation of 2,3-diaminotoluene and 4-trifluoromethylbenzaldehyde afforded 4-methyl-2-(4-trifluoromethylphenyl)benzimidazole. Oxidation of the methyl group with potassium permanganate in warm t-butanol afforded the carboxylic acid that was converted to the corresponding carboxamide
提出了一种四步合成PARP抑制剂2-(4-三氟甲基苯基)苯并咪唑-4-羧酰胺(1,NU1077)。2,3-二氨基甲苯和4-三氟甲基苯甲醛的缩合得到4-甲基-2-(4-三氟甲基苯基)苯并咪唑。在温暖的叔丁醇中用高锰酸钾氧化甲基,得到羧酸,其通过酰氯转化为相应的羧酰胺。
