5-Methyl-1H-indazole is a diazonium salt that can exist in two tautomeric forms: the keto form and the enol form. 5-Methyl-1H-indazole is a hypotensive drug that mediates its effects through a nucleophilic attack on the imidazoline ring. This mechanism has been studied kinetically, yielding isolated yields of 5-methyl-1H-indazole and its tautomeric form. Refluxing 5-methyl-1H-indazole with nitrobenzene at 170°C for 12 hours leads to the production of a yellow liquid, which crystallizes as an off white solid. The structure of this solid was determined by spectroscopies such as IR, UV, and NMR.
