Procedure

2,2-Dimethoxypropane and pyridinium p-toluenesulfonate are added to a solution of (S)-3-(1-iodocyclopropyl)propane-1,2-diol dissolved in dichloromethane and the mixture stirred at room temperature for 2 hours. Solvents are removed under reduced pressure and the crude product purified by flash chromatography using ethyl acetate/hexane (1:10) eluant.
