Reaction Steps

A mixture of liquid ammonia (30 ml) and ethyl 3-amino-4-cyanopyridine-2-carboxylate (Preparation 11; 2.8 g, 0.0147 mol) was heated at 100° C. in an autoclave for 18 hours. The ammonia was allowed to evaporate and the resulting product crystallised from ethyl acetate to give the title compound as an off-white solid (2.2 g, 94%), m.p. >310° C. Found: C,51.84; H,3.69; N,34.30. C7H6N4O requires C,51.85; H,3.73; N,34.56%.
