YieldReaction ConditionsOperation in experiment
80% With pyridine; at 20.0℃; for 1.5h; Methyl 3-hydroxy-1H-indazole-5-carboxylate (1.60 g, 8.33 mmol) was suspended in pyridine (10 mL). Ethyl chloroformate (0.90 mL, 9.3 mmol) was added slowly and the reaction was stirred at room temperature for 1 hour. Additional ethyl chloroformate (0.30 mL, 3.1 mmol) was added and the reaction was stirred for another 30 minutes. The reaction was poured into water (65 mL) and cooled in a refrigerator for 3 hours. The brown solid was collected by filtration, rinsed with water, and dried under vacuum to give the title compound (1.75 g, 80%). +ESI (M+H) 265.1; 1H NMR (400 MHz, CDCl3, delta): 8.56 (s, 1H), 8.29 (d, J=7.8 Hz, 1H), 8.13 (br. s., 1H), 4.59 (q, J=7.0 Hz, 2H), 3.97 (s, 3H), 1.56 (t, J=7.0 Hz, 3H).

YieldReaction ConditionsOperation in experiment
99% With hydrogenchloride; In water; at 100.0℃; for 6.0h; 3-hydroxy-1H-indazole-5-carboxylic acid (1.5 g, 8.4 mmol) was suspended in methanol (17 mL). Concentrated hydrochloric acid (3.11 mL, 101 mmol) was added and the reaction was heated to 100 C. for 6 hours. The reaction was concentrated to provide the title compound (1.60 g, 99%). +ESI (M+H) 193.1; 1H NMR (400 MHz, DMSO-d6, delta): 12.00 (br. s., 1H), 8.35 (s, 1H), 7.83 (dd, J=8.9, 1.7 Hz, 1H), 7.33 (dd, J=8.9, 0.7 Hz, 1H), 3.82 (s, 3H).
