反応手順
To 5-fluoro-2-nitrophenol (8.3 g, 52.83 mmol) in 50 mL of DMF was added K2CO3 (14.6 g, 105.7 mmol), and ethyl iodide (8.53 mL, 105.7 mmol). The mixture was stirred at 60° C. for 24 h in a sealed tube. The mixture was poured into 500 mL of H2O and extracted with diethyl ether, dried (Na2SO4), filtered, and rotovaped down to give the title compound of step A (9.69 g, 52.33 mmol, 99%). 1H NMR (400 MHz, CDCl3) δ ppm 7.88-7.94 (m, 1H), 6.71-6.77 (m, 1H), 6.66-6.71 (m, 1H), 4.11-4.19 (m, 2H), 1.45-1.51 (m, 3H).
