Participants

Reaction Steps

To a solution of the compound (150 mg, 0.594 mmol) of Example 16-4 in dicloromethane (2 ml) were added carbon tetrabromide (207 mg, 0.623 mmol) and triphenylphosphine (163 mg, 0.623 mmol), and the mixture was stirred for 30 minutes at room temperature. By adding ether to the reaction mixture, the resulting precipitate was filtered off. The filtrate was concentrated and the residue was purified with silica gel chromatography (hexane:ethyl acetate=2:1) to give the subject compound (141 mg, 75.3%).
