Participants

Reaction Steps

A solution of 4-methyl-3-nitroaniline (3.60 g, 23.7 mmol) in acetic anhydride (28 mL) was allowed to stir at room temperature. After 16 h, the reaction mixture was concentrated in vacuo, diluted with ethyl acetate (25 mL), washed with saturated sodium bicarbonate (2×50 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to give 4.20 g (Y: 99%) of the title compound; 1H-NMR (CDCl3): δ 8.10 (d, J=1.7 Hz, 1H), 7.75 (dd, J=8.5, 1.7 Hz, 1H), 7.38 (bs, 1H), 7.29 (d, J=8.5 Hz, 1H), 2.56 (s, 3H), 2.21 (s, 3H); MS (DCI) m/e: 195 (MH+).
