Participants

Reaction Steps

A solution of 1.06 g of the compound obtained in Example 13a in 20 ml of dichloromethane was added with 1.8 g of carbon tetrabromide and 1.4 g of triphenylphosphine and stirred for 1 hour. The reaction mixture was added with saturated aqueous NaOH for washing. The solvent was evaporated under reduced pressure and the resulting residue was purified by silica gel column chromatography (ethyl acetate) to obtain 1.2 g of the title compound (yield: 91%).
