Procedure

A solution of pyridine-2-carbonitrile 20 g (192 mM), hydrazine hydrate (3 eq.) in ethanol (50 ml) is stirred at room temperature for 18 hrs. Reaction mass is then diluted with water, extracted with ethyl acetate, dried over anhydrous sodium sulphate and concentrated under vacuum to yield desired compound.
