The reactor containing this mixture was heatedto 50 C in an oil bath under vigorous stirring and then 30% H2O2(30 mL, 0.3 mol) was slowly dropwise over a period of 30 min. The mixture was stirred for 5 h. After filtering, the solution wasevaporation under reduced pressure at 50 C. Pure 1H-benzo[d]imidazole-2-carbaldehyde (0.07 mmol, 10.2 g) was obtained with ayield of 70% after recrystallisation from 30% H2SO4 solution. Theproduct, 1H-benzo[d]imidazole-2-carbaldehyde, was identified byits 1H NMR spectrum.
