GENERAL METHOD: To a cooled DMF solution, methyl 1H-indazole-5-carboxylate (1.0 eq.), K2CO3 or KOH (ca. 3 eq.), and I2 (2-4 eq.) were sequentially added at 0 °C. The reaction mixture was stirred under cooling conditions or at room temperature for several hours. Upon completion of the reaction, the reaction is quenched with an excess of 10% aqueous NaHSO3, followed by dilution with H2O. In most cases, the precipitate is collected by filtration and washed with H2O to give methyl 3-iodo-5-indazolecarboxylate of the desired purity. | [References]
