HCID 132411182-Nitropyridine-4-carboxamide

Procedure

A mixture of 400 mg. of methyl 2-nitroisonicotinate and 2 ml. of 28% aqueous ammonia were stirred at room temperature for 1 hour. The solvent was distilled off, and the residue was recrystallized from ethanol-ether to give 348 mg. of the desired product.
