Reaction Steps

To a solution of (S)-methyl 2-(3,4-difluorophenyl)-3-(2-methylpyrrolidin-1-yl)quinoxaline-6-carboxylate (80 mg, 0.23 mmol) in methanol (10 mL) was added sodium hydroxide (40 mg, 1 mmol). 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 to 6 with 3N HCl, and filtered to give (S)-2-(3,4-difluorophenyl)-3-(2-methylpyrrolidin-1-yl)quinoxaline-6-carboxylic acid as a light yellow solid (44.5 mg, 58%).
