실험 절차

3-Oxo-2,3-dihydro-1H-indazole-6-carboxylic acid (1.5 g, 8.4 mmol) was suspended in methanol (17 mL). Concentrated hydrochloric acid (3.1 mL, 101 mmol) was added and the reaction was heated to reflux for 24 hours. The reaction was concentrated to give the title compound (1.6 g, 100%). +ESI (M+H) 193.1; 1H NMR (400 MHz, DMSO-d6, δ): 11.98 (br. s., 1H), 7.89 (s, 1H), 7.72 (d, J=8.6 Hz, 1H), 7.50 (dd, J=8.5, 1.3 Hz, 1H), 3.85 (s, 3H).
