실험 절차

To a solution of 9.59 g of 2-chloro-3-fluoropyridine in 6 ml of ethanol there was added 6 ml of hydrazine monohydrate, and the mixture was stirred at 60° C. for 3 days. The solution was adsorbed onto 50 g of NH silica gel and purified by NH silica gel column chromatography (ethyl acetate-heptane) to give the title compound (403 mg) as a yellow solid.
