Procedure

To a solution of 4-methoxyphenol (500 mg, 4.03 mmol) in CH3CN (10 mL) was added ethyl 2-bromo-2-methylpropanoate (807 mg, 4.84 mmol) and K2CO3 (3 g, 21.7 mmol) at 25° C. The mixture was refluxed for 16 h. The mixture was then diluted with water (100 mL), extracted with ethyl acetate (2×50 mL) and the combined organic layers washed with brine (30 mL), dried over Na2SO4 and concentrated to give the title compound which was used in next step without further purification.
