Procedure

Dimethylamine (50% aqueous solution, 3.6 ml) was stirred in an ice bath and a solution of 3-nitrobenzoyl chloride (1.8 g) in 1,4-dioxan (4 ml) was dropwise added thereto. The resulting mixture was stirred vigorously at ambient temperature for 2.5 hours. Ethyl acetate was added and organic layer was washed with water, 1N hydrochloric acid, 1N sodium hydroxide, water and saturated sodium chloride solution successively and dried over anhydrous magnesium sulfate. After filtration and concentration, the residue was recrystallized from benzene-n-hexane to afford N,N-dimethyl-3-nitrobenzamide (1.5 g) as a pale yellow prism.
