실험 절차

To a solution of 4-fluorophenol (0.49 g, 4.4 mmol) in DMF (10 mL) cooled to 0° C. was added 60% sodium hydride (0.19 g, 4.8 mmol) was added and the reaction was warmed to ambient temperature. 5-Bromo-3-nitropicolinonitrile (1.0 g, 4.4 mmol, solution in 5 mL DMF) and stirred for 3 hours. Poured into water, filtered, washed with water, and dried to yield the title compound (1.0 g, 78%).
