실험 절차

To a solution of 4-fluoro-3-nitrobenzonitrile (10 g, 0.06 mol) in THF (50 mL) was added in portions, via syringe, 3-aminopropanol (5 mL, 0.07 mol) and the mixture was stirred at room temperature. After one hour of reaction the crude mixture was evaporated to dryness and AcOEt was added (300 mL). The organic layer was washed with aqueous sodium bicarbonate (250 mL of a 4% aqueous solution) and the aqueous phase was further extracted with AcOEt (2×100 mL). The combined organic extracts were washed with brine, dried over anhydrous sodium sulphate, and concentrated under reduced pressure to give the title compound as an orange solid (13.4 g, 99% yield) which was used in the next step without further purification.
