Procedure

Methyl α-phenylthio-α-(m-phenoxyphenyl)propionate (210 mg) was dissolved in 1 ml of ethanol. An ethanol suspension (5 ml) of 2 cc of Raney nickel (W-II) was added, and the mixture was stirred at room temperature for 5 hours. The reaction mixture was filtered, and the insoluble matter was washed with 50 ml of methanol. The filtrate and the washing were combined, and concentrated under reduced pressure. Methylene chloride (30 ml) was added to the residue, and the insoluble matter was separated by filtration. The filtrate was concentrated under reduced pressure, and the residue was chromatographed on a column of silica gel using benzene as an eluent to afford 134 mg of methyl α-(m-phenoxyphenyl)propionate in a yield of 90%.
