実験手順

To tetrahydrofuran (1 ml) solution of 1-(2-cyanoethyl)-4-nitro-2-(4-nitrophenylthio)imidazole (27 mg) was added 1,8-diazabicyclo[5.4.0]undecene-7 (0.02 ml) at a room temperature, and stirred at the same temperature for 3 hours. To the reaction mixture were added 1N hydrochloric acid (0.7 ml), water and ethyl acetate, then the organic layer was taken by liquid separation. The ethyl acetate layer was washed with water and an aqueous solution being saturated with sodium chloride, then dried over anhydrous sodium sulfate. The residue obtained by removal of the solvent by distillation was purified by use of a thin layer chromatography (eluent: dichloromethane/ethyl acetate=9/1), there was obtained 4-nitro-2-(4-nitrophenylthio)imidazole (13 mg, yield 58%) as reddish brown powdery product.
