YieldReaction ConditionsOperation in experiment
With sodium hydroxide; water; In ethanol; at 80℃; for 4h; A mixture of 1H-indazole-6-carbonitrile (1-3, 1.50 g, 10.5 mmol, 1.00 equiv), and sodium hydroxide ( 1.26 g, 31.4 mmol, 3 equiv) in a 1 : 1 mixture of ethanol and IN aqueous sodium hydroxide (5 mL) was heated to 80 °C for 4 h. The reaction mixture was partitioned between saturated aqueous sodium bicarbonate solution and ethyl acetate (4 x 50 mL). The organic layer was discarded and the aqueous layer was acidified to pH 5 and washed with ethyl acetate (2 x 50 mL). The combined organic layers were dried over sodium sulfate and concentrated to give 1H-indazole-6-carboxylic acid (4- 1) as an off-white solid. The LRMS m/z (M+H ) 163.1 found, 163.0 required.
