How is 5-Methoxy-1H-indazole (CAS: 94444-96-9) typically synthesized?

5-Methoxy-1H-indazole is typically synthesized via the methylation of indazole or its intermediates. Common methods include the reaction of indazole with methanol in the presence of a base, such as potassium hydroxide, followed by acidification to obtain the desired methoxy derivative. Other synthetic routes involve the use of methylation reagents like dimethyl sulfate or methyl iodide, often catalyzed by Lewis acids, to selectively introduce the methoxy group into the indazole ring.
