Reaction Conditions

Reaction Steps

A solution of the product from Step 5 (1.02 g, 1.51 mmol) in PhMe (30 mL) was degassed for 30 minutes by bubbling nitrogen. Tri-n-butylvinyltin (533 μL, 1.81 mmol) and tetrakis(triphenylphosphine)palladium (175 mg, 0.151 mmol) were added, and the reaction mixture was heated to 105° C. for 3 hours, then cooled to RT for 18 hours. The volatiles were evaporated, and the residue was purified by chromatography on silica (20-50% EtOAc/hexane) to afford the title compound (820 mg) as a foam. LRMS ESI+ (M+H)+622.5.
