実験手順
2-(3,4-Diaminophenyl)benzonitrile (2.4 mmoles, 0.50 g) was dissolved in 3 ml ethanol. Ethyl phenylacetamidate hydrochloride (2.88 mmoles, 0.573 g) (prepared from HCl gas bubbled through benzyl cyanide and ethanol) was added. The reaction was warmed on a steam bath for 10 minutes. Ethyl acetate and brine were added. The organic phase was separated, dried and concentrated. The product was precipitated from ethyl acetate and hexane and filtered to yield 290 mg of 2-benzyl-5-(2-cyanophenyl)-1H-benzimidazole. (MS)
