28.8% | With caesium carbonate; In dimethyl sulfoxide; at 20 - 50℃; for 1h; | To a solution of 1-bromo-5-fluoro-2-methyl-4-nitrobenzene (10.0 g, 42.7 mmol) in DMSO (100 mL) was added Cs2CO3 (69.0 g, 214 mmol). CH3OH (10 mL) was added dropwise at rt and the resulting mixture was stirred at 50C for 1 hour. After TLC showed reaction completion, the reaction solution was diluted with ice water and extracted twice with EtOAc, washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (PE:EA = 3:1) to afford the compound 1-bromo- 5-methoxy-2-methyl-4-nitrobenzene as a yellow solid (3.0 g, 28.8 %). 1H NMR (400 MHz, DMSO-d6) δ 7.92 (d, J = 0.8 Hz, 1H), 7.60 (s, 1H), 3.92 (s, 3H), 2.33 (d, J = 0.6 Hz, 3H). |
