실험 절차
(2-Chloro-5-nitrophenyl)carbonimidic dichloride (17.8 g, 70.0 mmol) was dissolved in tetrahydrofuran (68 mL). The solution was added dropwise within 30 min to a solution of 1,4-butanediamine (30.9 g, 350 mmol) in tetrahydrofuran (168 mL) which was kept at 5-10° C. The reaction mixture was stirred for 1 h at 5-10° C. another 2 hr at room temperature. The suspension was filtered, and washed with tetrahydrofuran. The filtrate was concentrated in vacuo. The residue was taken up in water, filtered, and washed with water and disopropyl ether. After drying at 50° C. under vacuum, the title compound (8.9 g, 33.4 mmol, 48%) was obtained as a yellow amorphous.
