How is 6-Phenyl-1H-indazole (CAS: 1260897-38-8) typically synthesized?

6-Phenyl-1H-indazole can be synthesized via the indazole synthesis route, where phenylacetyl chloride is condensed with indole in the presence of a base like sodium hydroxide. The reaction typically yields a mixture of isomers, and separation may be required. Alternatively, it can be prepared through the Curtius rearrangement of phenylphosphorane. The overall yield is moderate, around 50-70%, depending on the method and purity of the starting materials.
