실험 절차

A mixture of 1,2-Phenylenediamine (1.0 g, 12.0 mmol) and 4-chlorobutyric acid (1.5 mL, 15.17 mmol) were refluxed in 4N HCl (13 mL) for 16 hours under N2 to give the title compound as white solid (900 mg, 50%). 1H NMR (CD3OD) □2.04-2.08 (m, 2H), 2.97 (t, 2H, J=7.8 Hz), 5.64 (t, 2H, J=6.6 Hz), 7.15-7.21 (m, 2H), 7.47-7.49 (m, 2H); ES-MS m/z 177.1 (M+H).
