To a stirring suspension of 4-chloro-3-nitrobenzonitrile (7.30 g, 40 mmol) in isopropanol (30 mL) is added n-propylamine (9.87 mL, 120 mmol). The mixture is stirred at room temperature for 5 h, and the solid is then collected by filtration to give 4-n-propylamino-3-nitrobenzonitrile as a yellow solid. 1H NMR (CDCl3) δ 8.51 (1H, q), 8.42(1H, br s), 7.60(1H, m), 6.91(1H, d), 3.33(2H, q), 1.84-1.74(2H, m), 1.07(3H, t). LRMS 206.3 (MH+).
