실험 절차

To a solution of cyclohexylamine (1 ml) and triethylamine (1.7 ml) in dichloromethane (20 ml) was added a solution of [2,1,3]-benzoxadiazole-5-carbonylchloride (730 mg, 4 mmol) in dichloromethane (10 ml). After stirring the mixture for 1 hour, the organic phase was washed with 1N HCl and conc. NaHCO3 solution, dried over magnesium sulfate, and concentrated under vacuum. The residue was triturated with ether to give a white solid (265 mg, yield=27%). Mp=172-173° C., 1H NMR (300 MHz, CDCl3) δ 8.15 (s, 1H), 7.90 (d, 1H, J=9.0 Hz); 7.82 (d, J=9.0 Hz, 1H); 6.09 (“s”, NH, 1H), 4.05-3.97 (m, 1H) and 2.09-1.18 ppm (m, 10H).
