실험 절차

A suspension of ethoxy[3-(4-fluorophenyl)(1H-indazol-5-yl)]methanimine hydrochloride (0.500 g, 1.56 mmol) and N-aminopyrrolidin-2-ylcarboxamide (0.606 g, 4.69 mmol) in 4 mL of anhydrous methanol was prepared. An excess of a commercial solution of sodium methoxide in methanol (0.727 mL, 4.37 M) was added. After 2 h, the temperature was raised to reflux and was maintained for 48 hours. The analysis of the mixture showed the formation of the corresponding oxodiazole occurring as a side reaction. The reaction was then quenched with water, the pH adjusted to neutral and the crude product extracted with ethyl acetate. The title compound was purified by preparative HPLC (0.030 g, 5% yield): 1H NMR (CD3OD) δ 8.69 (t, 1H), 8.10–8.02 (m, 3H), 7.68 (d, 1H), 7.05 (t, 2H), 4.52 (t, 1H), 3.17 (m, 2H), 2.39–1.99 (m, 4H), 2.37 (s, 6H), 2.30 (s, 2H), 1.12 (s, 9H); ES-MS (m/z) 349 [M+H]+.
