Reaction Steps

Benzyl bromide (17.5 ml, 0.147 mol) was added to a mixture of 1-(5-chloro-2,4-dihydroxyphenyl)ethanone (11 g, 0.059 mol) and potassium carbonate (20.34 g, 0.147 mol) in acetonitrile (180 ml). The mixture was stirred at reflux for 6 h and then allowed to cool to RT and stirred overnight. The mixture was filtered, and the solid residue was rinsed with DCM (3×50 ml). The combined organic filtrates were evaporated under vacuo to give a pale yellow solid. The latter was triturated with a mixture of hexane/EtOAc (175/7.5) and filtered to afford the title compound 1-[2,4-bis(benzyloxy)-5-chlorophenyl]ethanone (20.4 g, 93% yield) as an off-white solid.
