Procedure

A flask with a stirring bar was charged with a mixture of compound 1 (1.000 g, 1.54 mmol), PdCl2(PPh3)2 (0.0588 g, 0.065 mmol), a few crystals of 2,6-ditert-butylphenol, and toluene (15.0 mL). The mixture was heated to 100° C. under nitrogen, and tributylvinyltin (1.125 g, 3.534 mmol) was added dropwise. The mixture was further heated for 23 hours. It was subsequently diluted with 60 mL of ether and treated with KF solution (˜10%). The mixture was stirred for 20 hours and followed by filtration to remove the insoluble solid. The organic layer was washed with water and dried over anhydrous MgSO4. After removal of the solvent, the residue was purified by column chromatography with n-hexane as eluent to afford 0.650 g of compound 2.
