Reaction Steps
A mixture of 500 mg 6-hydroxy-2,2-dimethyl-benzo[1,3]dioxin-4-one (2.57 mmol), 550 mg benzyl bromide (3.22 mmol), and 922 mg cesium carbonate (2.8 mmol) in 8.6 mL of anhydrous DMF were stirred at room temperature for 18 hours. The mixture was diluted with ethyl acetate and washed successively with water, saturated sodium bicarbonate, and brine solutions. The organic fraction was dried over sodium sulfate and concentrated under reduced pressure to give a crude residue which was further purified by column chromatography, eluting from silica gel with a gradient of 10 to 50% ethyl acetate in hexanes, to give the desired product as a pale yellow solid.
