A solution of 3-methyl-4-nitrobenzyl bromide (1.0 g, 4.3 mmol), anhydrous dimethylamine (0.34 mL, 5.1 mmol) and potassium carbonate (1.5 g, 0.011 mol) in N,N-dimethylformamide (4.5 mL) was stirred at 70° C. for 12 h. Cooled to ambient temperature, the reaction mixture was poured into ice water, extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated to afford N,N-dimethyl-1-(3-methyl-4-nitrophenyl)methanamine as oil (0.80 g, y. 95%).
