Reaction Conditions

Reaction Steps

Resorcinol monoacetate (10.0 g, 65.7 mmoles) in anhydrous DMF (100 mL) was treated with K2CO3 (18.2 g, 131 mmoles) and allyl bromide (6.83 mL, 78.9 mmoles). The mixture was heated at 80° C. overnight, cooled to room temperature, and diluted with ethyl acetate. The mixture was washed with H2O, brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, 8% to 10% ethyl acetate:hexanes) to provide the title compound as a colorless oil (7.19 g, 57%). MS (DCI) m/z 193 (M+H)+.
