Reaction Steps

To a stirred solution of 7-hydroxy-1-tetralone (13.9 g, 85.7 mmol) and 1-bromo-2-(bromomethyl)-4-chlorobenzene (25.6 g, 90.0 mmol) in dimethylformamide (850 mL) was added potassium carbonate (24 g, 172 mmol). The reaction was stirred under argon for 18 hours then diluted with ethyl acetate (1 L). The organics were washed three times with water and once with brine. The organic layer was then dried with magnesium sulfate, filtered and concentrated. To the resulting oil was added methanol (500 mL) and the suspension was agitated for thirty minutes. 7-(2-bromo-5-chlorobenzyloxy)-3,4-dihydronaphthalen-1(2H)-one (27.8 g, 89% yield) was isolated by filtration.
