Procedure

To a solution of methyl 2-(5-fluorobenzo[b]thiophen-2-yl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylate (148 mg, 0.36 mmol) in tetrahydrofuran (25 mL) was added sodium hydroxide (43.4 mg, 1.08 mmol) and water (2 mL) with stirring overnight at room temperature. The reaction mixture was concentrated under vacuum, dissolved in water (20 mL) and adjusted to pH 5 with hydrochloric acid (3N). The solids were collected by filtration to afford 2-(5-fluorobenzo[b]thiophen-2-yl)-3-(isopropyl(methyl)amino)quinoxaline-6-carboxylic acid (69 mg, 49%).
