How is 3-iodo-1H-indazol-4-amine (CAS: 885521-28-8) typically synthesized?

3-Iodo-1H-indazol-4-amine is typically synthesized through a multistep process involving the condensation of indazole-4-carboxylic acid with iodomethane followed by reduction to form the amine. Other methods may involve the direct substitution of a nitrogen atom in an indazole derivative with iodine using a suitable catalyst and selective conditions to achieve high yield.
