Reaction Steps
A solution of 4,5-dimethyl-2-nitroaniline (2.00 g, 12 mmol) in toluene (25 mL) was added NaOH (1.93 g, 48 mmol). The reaction mass was stirred at 100° C. for 1 h, followed by addition of dimethyl sulphate (4.6 g, 36 mmol) and reaction mass was stirred at RT for 24 h. The reaction mass was quenched in water, extracted with DCM and concentrated to afford 1.5 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 2.11 (s, 3H), 2.24 (d, J=7.8 Hz, 3H), 2.92 (s, 3H), 6.77 (m, 1H), 7.79 (m, 1H), 8.06 (s, 1H); MS (m/z): 180.92 (M+H)+.
