Acetic Anhydride → HCID 59410103, compound

Participants

Reaction Steps

To a solution of 4-cyclohexyl-3-nitro-aniline (1.54 g, 6.99 mmol) in DCM (15 mL) was added Et3N (1.9 mL, 13.63 mmol), followed by the addition of acetic anhydride (3.3 mL, 34.98 mmol). The reaction mixture was stirred at room temperature for 2 h, quenched with water, the layers separated and the organic layer was washed with 0.1N HCl, followed by washing with H2O. The organic layer was dried over MgSO4, filtered and concentrated to obtain N-(4-cyclohexyl-3-nitrophenyl)acetamide (1.7 g, 93%). 1H NMR (400 MHz, CDCl3) δ 7.91 (d, J=2.2 Hz, 1H), 7.69 (dd, J=8.6, 2.2 Hz, 1H), 7.52 (s, 1H), 7.40 (d, J=8.6 Hz, 1H), 3.01-2.87 (m, 1H), 2.22 (s, 3H), 1.95-1.78 (m, 5H), 1.42 (t, J=10.4 Hz, 4H), 1.32-1.21 (m, 1H).
