To a solution of 4-fluoro-3-nitro-benzaldehyde (570 g, 3.3 mmol) in THF (20 mL) was added NH4OH (5 mL). The reaction mixture was stirred at room temperature for 1 hour. The resulting yellow solid was collected and washed with water, dried under vacuum to give the title compound (300 mg, yield: 53%). 1H-NMR (300 MHz, DMSO-d6) δ 9.76 (s, 1H), 8.57 (d, 1H), 8.18 (br s, 2H), 7.80 (dd, 1H), 7.10 (d, 1H).
