A 2 M solution in hexane of trimethylsilyldiazomethane (0.072 mol, 36 mL) was added dropwise to a solution of 4-(bromoethyl)benzoic acid (15 g, 0.065 mol) in DCM (150 mL) and MeOH (36 mL). The resulting solution was stirred at RT for 2 h then was concentrated under reduced pressure to afford the title compound (15.8 g, 98%) as a pale yellow oil. 1H NMR (CDCl3) δ 3.2 (t, 2H), 3.6 (t, 2H), 3.9 (s, 3H), 7.3 (d, 2H), 8.0 (d, 2H).
