Reaction Steps
To a solution of 4-fluorobenzonitrile (0.500 g, 4.13 mmol) in ethanol (3 mL) was added hydroxyl amine HCl (0.427 g, 6.19 mmol) and potassium carbonate (1.14 g, 8.26 mmol). The reaction mass was stirred at RT for 15-17 h. Excess of solvent was removed under vacuum. The obtained residue was diluted with water, acidified with dilute HCl and extracted with DCM. The organic layer was separated, dried over anhydrous sodium sulphate and concentrated to afford 0.450 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 5.84 (br s, 2H), 7.17-7.27 (m, 2H), 7.68-7.73 (m, 2H), 9.64 (br s, 1H); MS (m/z): 155.13 (M+H)+.
