実験手順
To a solution of dimethyl 2-chloro-6-fluoroterephthalate (6.19 g, 25.1 mmol) in tetrahydrofuran (75 mL) was added a solution of 1 N NaOH (27.6 mmol, 27.6 mL). The reaction mixture was stirred at room temperature for 30 min. After the volatiles were removed under reduced pressure, water (30 mL) was added. The aqueous solution was acidified with 1 N HCl to pH 3.0. A white solid precipitated and was collected by filtration, washed with water and diethyl ether, dried in high vacuum to afford the title compound as a white solid (5.54 g, 95% yield). 1H NMR (400 MHz, CDCl3) δ 7.96 (s, 1H), 7.76 (dd, J=8.8, 1.3 Hz, 1H), 4.01 (s, 3H). LCMS (APCI+) 233.0 [M+H]+.
