Procedure
3.92 g of the compound obtained in Step B are dissolved in 50 ml of acetonitrile, and then 5.31 g of triphenylphosphine and 6.71 g of carbon tetrabromide are added with stirring. After leaving at room temperature overnight, the acetonitrile is removed by evaporation in vacuo and the resulting residue is purified by chromatography over a column of silica gel (eluant: dichloromethane/methanol 96/4). Oil.
