実験手順

A mixture of ethyl pyridin-2-carboxylate (90 gm) and hydrazine (60 gm) in ethanol (400 ml) was stirred at 80° C. over a period of 4 h. Solvent was evaporated and to provide a crude mass. The mass was stirred with diethyl ether and the suspension was filtered and the wet cake washed with small quantity of ethanol (50 ml) to provide title compound in 76 gm quantity (93%) as a white solid.
