Reaction Steps
To a solution of methyl 2,7-dimethyl-2H-indazole-5-carboxylate (140 mg, 0.69 mmol) in methanol/water (V:V 1:1, 2 mL) was added LiOH (38 mg, 1.6 mmol). The solution was heated at 50° C. for 1 hour, cooled to room temperature, concentrated and acidified to pH 2 with KHSO4. The solid material was isolated by filtration to provide the title compound as a white solid (140 mg, 107%).
