To a solution of methyl 2-(1,3-benzothiazol-2-yl)-3-[(2S)-2-methylpyrrolidin-1-yl]quinoxaline-6-carboxylate (80 mg, 0.20 mmol) in tetrahydrofuran (20 mL) was added NaOH (23.8 mg, 0.60 mmol) and water (1 mL). The resulting solution was stirred overnight at room temperature and then concentrated in vacuo, adjusted the pH to 7 with HCl (3 N). The product was collected and filtered to afford 2-(1,3-benzothiazol-2-yl)-3-[(2S)-2-methylpyrrolidin-1-yl]quinoxaline-6-carboxylic acid as a light yellow solid (43.8 mg, 57%).
