実験手順

To a solution of methyl 3-(tert-butylamino)-2-(4-fluorophenyl)quinoxaline-6-carboxylate (120 mg, 0.34 mmol) in THF (20 mL) and water (2 mL) was added sodium hydroxide (54.39 mg, 1.36 mmol) with stirring overnight at room temperature. The reaction mixture was concentrated in vacuo, dissolved in water (30 mL), adjusted to pH 4 with HCl (3N) to give the precipitate, which was collected by filtration to afford 3-(tert-butylamino)-2-(4-fluorophenyl)quinoxaline-6-carboxylic acid as a light yellow solid (80 mg, 66%).
