Procedure
Sodium (18 mmol) is added to a flask containing 20 ml of ethanol. After the sodium has dissolved, 3.8 mmol of 5-carboxy-2-cyanopyridine and 18 mmol of hydroxylamine hydrochloride are added, and the solution is refluxed for 5 h. After cooling, the resulting precipitate is filtered off and recrystallized from water; m.p.>300°.
