Procedure

To a solution of (c) (1 g, 4.3 mmol) and vinyltributyltin (1.5 mL, 5.17 mmol) in degassed toluene (20 ml) was added tetrakis(triphenylphosphine) palladium (0) (245 mg, 5 mol %) and the mixture was refluxed under argon for 2 hours. Evaporation and flash silica chromatography eluting with chloroform afforded the product as a pale yellow solid (500 mg, 64%).
