실험 절차

3-(2-Cyanophenyl)-5-(2-pyridyl)-2 (1H)-pyridone (46 mg), 36 mg of benzyl alcohol and 88 mg of triphenylphosphine were dissolved in 2 ml of tetrahydrofuran, 147 mg of a 40% solution of diethylazo dicarboxylate in toluene were added with ice cooling and the mixture was stirred at room temperature for 1 hour. The reaction solution was concentrated in vacuo and purified by a silica gel chromatography (hexane-ethyl acetate system) to give 12 mg of the title compound.
