실험 절차

5-(Bromo-m-tolyl-acetyl)-3-methyl-1-phenyl-1,3-dihydro-benzoimidazol-2-one (prepared from 2-oxo-1-phenyl-2,3-dihydro-1H-benzoimidazole-5-carboxylic acid methoxy-methyl-amide as described in the general procedure, 0.26 gm, 0.60 mmol) was added to 5 mL of 8% water/formamide and the mixture was heated to 140° C. for 14 hours. The reaction mixture was then cooled to room temperature and diluted with 20 mL of ammonium hydroxide with rapid stirring. After stirring for ½ hour, the solid precipitate was filtered and purified by column chromatography (0.5% methanol in ethyl acetate) to afford 75 mg of the title compound. MS (M+1)=381.2
