Procedure

To a solution of methyl 3-(6-fluoro-1,2,3,4-tetrahydroquinolin-1-yl)-2-(4-fluorophenyl)quinoxaline-6-carboxylate (88 mg, 0.18 mmol) in methanol (25 mL) and water (1 mL) was added sodium hydroxide (24.5 mg, 0.61 mmol) with stifling overnight at room temperature. The reaction mixture was concentrated under vacuum, dissolved in water (10 mL), adjusted to pH 4 with hydrochloric acid (3 N) to give the precipitation, which was collected by filtration to afford 3-(6-fluoro-1,2,3,4-tetrahydroquinolin-1-yl)-2-(4-fluorophenyl)quinoxaline-6-carboxylic acid as a yellow solid (63 mg, 79%).
