Reaction Steps

Allyl bromide (25.53 ml; 302 mmol) was added slowly to a mixture of the compound of example 65b (75 g; 251.4 mmol), K2CO3 (52.04 g; 377 mmol) and KI (˜1 g) in DMF (150 ml) under vigorous stirring for 15 min at room temperature. The reaction mixture was stirred overnight (˜16 h), treated with water (1 lit.), and extracted with EtOAc. The EtOAc layer was washed with water, brine, dried (Na2SO4), concentrated and purified using flash chromatography (silica gel, 3% CH3CN in chloroform) to obtain the title compound as an oil. Yield, 76 g (89.7%); MS (EI): 337 (M+), 136.
