반응 단계
To 1-bromo-2,5-difluoro-4-nitrobenzene (5.0 g, 21 mmol) was added 0.5 N sodium methoxide (50 mL, 25 mmol). The mixture was stirred at 60° C. for 1 h. The MeOH was rotovaped down. The crude product was dissolved in DCM (100 mL), washed with H2O, dried (Na2SO4), filtered, and rotovaped down to give the title compound of step A (5 g, 20 mmol, 95%) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ ppm 7.69 (s, 1H), 7.28 (s, 1H), 3.95 (s, 3H).
