Procedure
Cesium carbonate (5.7 g, 17.5 mmol) was added to a stirred solution of 4-hydroxypropiophenone (12; 2.5 g, 16.7 mmol) in dimethylformamide (25 mL) under nitrogen at room temperature, followed by bromomethyl methyl ether (1.43 g, 17.5 mmol). After 20 hours the mixture was stirred into 200 mL of water, and then extracted 3× with dichloromethane. The combined extracts were washed with water and then sat brine, and dried over magnesium sulfate. The solvent was removed in vacuo, leaving 3.4 g of pale yellow apparently crystalline solid; mp 31-35° C.; mass spec ES+m/z=209 (m+1).
