実験手順
2,3,6-Trifluorobenzonitrile (1.76 ml, 15.2 mmol) in aqueous ammonia (20 ml) and acetonitrile (10 ml) was stirred for 7 days. Water was added. The whole was extracted with ether, the ether was dried (sodium sulphate) and evaporated. Flash column chromatography on silica gel, eluting with dichloromethane, gave the product (1.2 g), MS (+EI) 154 (M+), 1H NMR (CDCl3) 7.07-7.16 (1H, m), 6.36-6.43 (1H, m), 4.62 (2H, s).
