Procedure

To a solution of (±)-1-acetoxy-1-(3-carbamylmethoxyphenyl)-2-phenyl-2-(1,3-dithian-2-yl)-ethane (110 mg, 0.26 mmol) in 5 mL 9:1 (v/v) acetonitrile/water was added mercuric perchlorate (148 mg, 0.33 mmol). The solution was stirred for 15 min, filtered through a 0.45 mm PTFE syringe filter (Gelman) into a 5% sodium bicarbonate solution (10 mL), and extracted with 50 mL dichloromethane. The organic phase was dried and evaporated under reduced pressure to yield a colorless oil. Samples for analysis were evaporated from methanol, dissolved in warm water and lyophilized. Yield: 65 mg (76%).
