  • (E)-1-methyl-2-((2-(4-(trifluoromethoxy)phenyl)hydrazono)methyl)-1H-benzo[d]imidazole [ No CAS ]
YieldReaction ConditionsOperation in experiment
68.2% In methanol; at 20℃; for 2h; General procedure: The equimolar aldehyde 3a-3d (1 mmol) and substituted phenylhydrazine 5a-5s (1 mmol) weremixed in CH3OH (10 mL) and stirred at room temperature [18]. After about 2 h, the reaction wascompleted (monitored by TLC). The residual crude was purified via silica gel column chromatogramusing a gradient mixture of petroleum ether and ethyl acetate to obtain the pure target compounds6a-6ai (in 45-80% yield).
