Reaction Conditions

Reaction Steps

A mixture of acetic anhydride (49 mL, 0.5 mol) and formic acid (19 mL, 0.5 mol) was heated at 60° C. for 3 h. 5-Fluoro-3-nitropyridin-2-amine was added and the mixture was stirred at 60° C. for 1 h. The mixture was concentrated under reduced pressure and the residue was stirred vigorously in diethyl ether (200 mL) for 30 minutes. The solid was collected by filtration to afford N-(5-fluoro-3-nitropyridin-2-yl)formamide (4.5 g, 96%) as an orange solid which did not require further purification. LCMS (ESI) m/z 186 (M+H)+.
