Ammonium Acetate → 4-(Pyridin-2-ylmethoxy)pyridin-2(1H)-one

Participants

Reaction Steps

2-Chloro-4-(pyridin-2-ylmethoxy)pyridine (4.10 g, 18.5 mmol) and ammonium acetate (7.21 g, 92.3 mmol) were heated to 110° C. in a mixture of formic acid (20 mL) and water (20 mL) for 5 days. The mixture was concentrated to remove most of the liquid and then adjusted to pH 8 with NaHCO3 solution. The resulting solid was filtered off to provide the title compound (3.1 g, 83%) as a white solid: ESI MS m/z 203 [M+H]+.
