실험 절차
A mixture of 2-fluoro-6-iodobenzonitrile (2 g, 8.1 mmol) and hydrazine hydrate (4 mL) in n-butanol (40 mL) was heated to 105-110° C. for 5 hours, cooled to room temperature, poured into water, and extracted twice with ethyl acetate. The combined extracts were washed with water and brine, dried (MgSO4), filtered, and concentrated to provide 1.88 g of the desired product. Rf=0.25 (5% methanol/dichloromethane).
