Reaction Steps

To a solution of methyl 2-(3-methyl-1H-indazol-5-yl)-3-(3-methylbutan-2-yl)quinoxaline-6-carboxylate (85 mg, 0.22 mmol) in methanol (20 mL) and water (1 mL) was added sodium hydroxide (18 mg, 0.45 mmol). After stirring overnight at room temperature, the reaction mixture was concentrated under reduced pressure to afford a residue, which was dissolved in water (20 mL), adjusted the pH value to 6 with 3N HCl and filtered to give 2-(3-methyl-1H-indazol-5-yl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylic acid as a light yellow solid (50.1 mg, 61%).
