To a solution of methyl 3-(azepan-1-yl)-2-(benzo[b]thiophen-2-yl)quinoxaline-6-carboxylate (82 mg, 0.2 mmol) in methanol (15 mL) was added sodium hydroxide (80 mg, 2 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 HCl (3 N) and filtered to give 3-(azepan-1-yl)-2-(benzo[b]thiophen-2-yl)quinoxaline-6-carboxylic acid as a light yellow solid (70.1 mg, 88%).
