Reaction Steps

To a solution of (S)-methyl 2-(1H-benzo[d][1,2,3]triazol-5-yl)-3-(2-methylpyrrolidin-1-yl)quinoxaline-6-carboxylate (130 mg, 0.33 mmol) in methanol (30 mL) was added sodium hydroxide (40.2 mg, 1.00 mmol) and water (1 mL) with stirring for overnight at room temperature. The resulting mixture was concentrated under vacuum and dissolved in water (25 mL), and adjusted to pH 4 with HCl (3N) to give the precipitate, which was collected by filtration to afford (S)-2-(1H-benzo[d][1,2,3]triazol-5-yl)-3-(2-methylpyrrolidin-1-yl)quinoxaline-6-carboxylic acid as a yellow solid (90.3 mg, 72%).
