実験手順
To 4-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)butyl)-1,2,4-triazolidine-3,5-dione (I-14b: 6 mg, 0.024 mmol) in CH2Cl2 (0.95 mL) was added SiO2-HNO3 (50 mg). The mixture was stirred at room temperature for 15 minutes, then filtered, concentrated in vacuo and dried giving 4-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)butyl)-3H-1,2,4-triazole-3,5(4 H)-dione (I-14c: 6 mg, quantitative) as a pink solid. 1H NMR (400 MHz, CD3CN) δ ppm 1.52-1.71 (m, 4 H) 3.49 (t, J=6.44 Hz, 2 H) 3.59 (t, J=6.69 Hz, 2 H) 6.77 (s, 2H).
