Reaction Steps

To a stirred solution of ethyl 2-(4-hydroxyphenyl)acetate (10 g, 0.05 mol) in acetonitrile (100 mL) were added K2CO3 (15.3 g, 0.11 mol) and dimethyl sulfate (8.4 g, 0.06 mol) under an inert atmosphere. The reaction mixture was stirred at 80° C. for 2 h and then extracted with EtOAc (2×300 mL), The combined organic layers were washed with water, dried over Na2SO4 and concentrated in vacuo to afford ethyl 2-(4-methoxyphenyl)acetate (8 g, 74%) as a white solid.
