YieldReaction ConditionsOperation in experiment
84% With iodine; potassium hydroxide; In N,N-dimethyl-formamide; at 25℃; for 3h; Into a 25-mL round-bottom flask was placed 1 H-indazole-5-carboxylic acid (200 mg, 1.23 mmol), Nu,Nu-dimethylformamide (3 ml_), potassium hydroxide (138 mg, 2.46 mmol) and iodine (470 mg, 1.85 mmol). The solution was stirred for 3 h at 25C. The reaction was quenched by the addition of 10 mL of Na2S203. The pH value of the solution was adjusted to 6 with hydrogen chloride solution (10 %). The solids were collected by filtration. This resulted in 300 mg (84%) of 3-iodo-1 H-indazole-5-carboxylic acid as a white solid
