실험 절차
To tert-butyl 4-(3,5-dioxo-1,2,4-triazolidin-4-yl)butylcarbamate (I-8b: 590 mg, 2.167 mmol) in CH2Cl2 (10.800 mL) was added HCl in dioxane (5.42 mL, 21.67 mmol) dropwise. The mixture was stirred at room temperature for 4 h, then concentrated and dried on pump, giving 4-(4-aminobutyl)-1,2,4-triazolidine-3,5-dione hydrochloride (I-14a: 461 mg, quantitative) as a beige solid. 1H NMR (400 MHz, dmso-d6) δ ppm 1.41-1.71 (m, 4 H) 2.68-2.87 (m, 2 H) 3.37 (t, J=6.44 Hz, 2 H) 7.86 (br. s., 2 H) 10.13 (s, 2 H).
