Reaction Steps

To a solution of 4-fluoro-2-methyl-1-nitro-benzene (300 mg, 1.84 mmol) in DMSO (2 mL) were added KOH (20 mg, 3.87 mmol) and imidazole (263 mg, 3.88 mmol). The reaction mixture was heated to 100° C. for 3.5 h, cooled to room temperature, and diluted with ice-cold water. The resulting precipitate was filtered, washed with ice-cold water, and dried under vacuum to give the title compound (310 mg, 80%) as a yellow powder. 1H NMR (300 MHz, DMSO-d6) δ 8.46 (1H, s), 8.16 (1H, d, J=8.9 Hz), 7.90-7.92 (2H, m), 7.78 (1H, dd, J=2.5, 8.9 Hz), 7.17 (1H, s), 2.61 (3H, s). LRMS (M+H)+mz 204.
