Participants

Reaction Steps

To a solution of methyl 3-(azepan-1-yl)-2-(2,2-difluoro-2H-1,3-benzodioxol-5-yl)quinoxaline-6-carboxylate (110 mg, 0.25 mmol) in methanol (30 mL) and water (1 mL) was added sodium hydroxide (40 mg, 1.00 mmol) with stirring overnight at room temperature. The resulting mixture was concentrated in vacuo and dissolved in water (10 mL), adjusted to 6 with HCl (3 N) and collected by filtration to give 3-(azepan-1-yl)-2-(2,2-difluoro-2H-1,3-benzodioxol-5-yl)quinoxaline-6-carboxylic acid as a yellow solid (70 mg, 66%).
