Procedure

To a solution of methyl 2-(4-fluorophenyl)-7-methoxy-3-[methyl(propan-2-yl)amino]quinoxaline-6-carboxylate (120 mg, 0.31 mmol) in methanol (30 mL) and water (1.0 mL) was added sodium hydroxide (50 mg, 1.25 mmol) with stirring overnight at room temperature. The reaction mixture was concentrated in vacuo, dissolved in water (30 mL), and adjusted to pH 5 with hydrochloric acid (3N) to give the precipitate, which was collected by filtration to afford 2-(4-fluorophenyl)-7-methoxy-3-[methyl(propan-2-yl)amino]quinoxaline-6-carboxylic acid as a light yellow solid (38.2 mg, 88%).
