Reaction Steps

To a solution of hydrazine (8 mL) in DME (40 mL) was added dihydroxypyridine (2.00 g, 18 mmol) and the reaction heated at reflux overnight. The solution was cooled to rt, and the solids removed by filtration. The filtrate was concentrated and the resulting solid crystallized from hot EtOH to afford 4-hydrazinylpyridin-2(1H)-one (1.75 g, 78% yield). LC-MS (ESI) m/z 126 (M+H)+.
