To a solution of 2-(3-methoxy-4-(trifluoromethyl)phenyl)acetic acid (17.0 g, 72.6 mmol) in MeOH (200 mL), thionyl chloride (10 mL, 141 mmol) was added dropwise. The resulting mixture was stirred at room temperature for 16 h and concentrated under vacuum to afford the title compound (18.8 g). 1H NMR (DMSO-d6): δ 7.49 (s, 1H), 7.40 (d, 1H), 6.96 (d, 1H), 3.87 (s, 3H), 3.68 (s, 3H), 3.64-3.58 (m, 2H).
