To a mixture of 5,5-diphenyl-2-cyclopentenyl acetate (0.30 g) and sodium azide (84 mg) in a solution of tetrahydrofuran (3 ml) and water (1.5 ml) was added tetrakis(triphenylphosphine)palladium(O) (62 mg) at room temperature under an argon atmosphere. After being stirred for 14.5 hours, ethyl acetate was added. The organic layer was separated, washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel with a mixture of n-hexane and ethyl acetate as an eluent to give 4,4-diphenyl-2-cyclopentenyl azide (0.16 g).
