3-Bromothiolan-2-one (315 mg) and ethyl 2-(4-formylphenyl)propionate (300 mg) were dissolved in tetrahydrofuran, and to the solution was added zinc (147 mg) and a catalytic amount of iodine, and the reaction mixture was heated until the mixture was refluxed. The reaction mixture was stirred overnight at room temperature, then the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=5/1) to give the title compound (106 mg, 20%).
