실험 절차

To a solution of 1-acetyl-3-(4-fluorophenyl)-1H-indazole-5-carbonyl chloride (100 mg, 0.33 mmol) in ethanol (40 mL) was added pyridine (0.5 mL). The reaction was stirred overnight at room temperature when saturated ammonium hydroxide (1 mL) was added. The reaction was stirred overnight when water (150 mL) was added and the solution filtered. The solid was dried to recover the product (100 mg, 100% yield). 1H NMR (DMSO-d6) δ 13.6 (s, 1H), 8.62 (s, 1H), 8.03–7.9 (m, 3H), 7.70 (d, 1H), 7.61 (d, 1H), 7.42 (t, 2H); ES-MS (m/z) 285 [M+1]+.
