実験手順

A solution of the product from Example 9A (0.48 g, 0.92 mmol) in THF (5 mL) was treated with vinyl chloroformate (0.10 mL, 0.94 mmol) and stirred at ambient temperature overnight. The solvent was evaporated and the residue was purified by flash chromatography over silica gel (ethyl acetate and then 10% ethanol/methylene chloride) to provide the title compound (0.25 g).
