Reaction Steps

To a solution of methyl 2-(4-fluorophenyl)-3-(methyl(tetrahydro-2H-pyran-4-yl)amino)quinoxaline-6-carboxylate (100 mg) in methanol (20 mL) was added sodium hydroxide (40 mg, 1.00 mmol) and water (1 mL). After stirring overnight at room temperature, the reaction mixture was concentrated under reduced pressure to afford a residue, which was dissolved in water (10 mL), adjusted the pH value to 6 with hydrochloric acid (3 N) and the product was precipitated to afford 2-(4-fluorophenyl)-3-(methyl(tetrahydro-2H-pyran-4-yl)amino)quinoxaline-6-carboxylic acid as a light yellow solid (52 mg).
