Reaction Steps

The product of example 16 (250 mg, 0.46 mmol), carbon tetrachloride (354 mg, 2.3 mmol) and triethylamine (116 mg, 1.15 mmol) were mixed in acetonitrile (15 ml). To the above mixture was added triphenylphosphine (302 mg, 1.15 mmol) at room temperature and stirred overnight. Then water (50 ml) was added and the mixture was extracted with dichloromethane three times. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and evaporated into dryness. The residue was subjected to silica gel chromatography using PE-ethyl acetate (1:4 v/v) as eluent to give the titled product (195 mg, 80.7%).
