Reaction Steps

To a solution of 3-fluoro-4-nitrobenzoic acid (4.0 g, 21.6 mmol) and EDC (1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride) (4.36 g, 28.1 mmol) in methylene chloride (100 mL) was added methylamine (11.3 mL of a 2 M solution in MeOH, 22.7 mmol) and the solution was stirred at room temperature overnight. The solution was washed with 1 N HCl, dried over MgSO4 and concentrated to a solid. The solid was triturated with butyl chloride and collected by filtration to give the N-methyl-3-fluoro-4-nitrobenzamide (3.81 g, 96%).
