実験手順
200 mg of 5-(4-aminophenyl)-8-methyl-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine is mixed in 30 ml of tetrahydrofuran with 1.32 ml of pentyl nitrite and refluxed under argon for 2 hours. After concentration by evaporation, it is chromatographed on silica gel with methylene chloride:ethanol=10:1. 136 mg of 8-methyl-5-phenyl-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine is obtained.
