To a solution of 5-methyl-2-nitro-phenylamine (3.04 g, 20.0 mmol) in anhydrous DMF (20 mL) at 0° C. was portionwise added 95% NaH (528 mg, 22.0 mmol) and the resulting mixture stirred for 10 min. A solution of iodomethane (1.25 mL, 20.0 mmol) in anhydrous DMF (10 mL) was then added. The ice bath was removed and the resulting mixture was stirred at room temperature overnight. The resulting mixture was diluted with water, the solid was collected by filtration, washed with H2O and hexanes to yield methyl-(5-methyl-2-nitro-phenyl)-amine MS 167 (M+1)+.
