How is 6-Methoxy-1H-indazol-5-amine (CAS: 749223-61-8) typically synthesized?

6-Methoxy-1H-indazol-5-amine is typically synthesized through a multi-step reaction involving the reaction of indole-3-carboxaldehyde with methanol in the presence of a suitable catalyst, such as p-toluenesulfonic acid. The reaction yields a high purity product with good selectivity and yield. Further purification can be achieved through recrystallization or column chromatography.
