Procedure

Into a 50-mL round-bottom flask, was placed a solution of methyl 3-(4-fluorophenyl)-2-(4-(4-methoxyphenyl)piperidin-1-yl)quinoxaline-6-carboxylate (123.9 mg, 0.24 mmol, 1.00 equiv, 93%) in methanol (15 mL). This was followed by the addition of a solution of sodium hydroxide (52.6 mg, 1.31 mmol, 5.00 equiv) in water (3 mL), which was added dropwise with stirring. The resulting solution was stirred for overnight at 50° C. in an oil bath. The pH value of the solution was adjusted to 3-4 with 1N hydrochloric acid. The resulting mixture was concentrated under vacuum. The resulting mixture was washed with methanol. This resulted in 60 mg (52%) of 3-(4-fluorophenyl)-2-(4-(4-methoxyphenyl)piperidin-1-yl)quinoxaline-6-carboxylic acid as a yellow solid.
