Reaction Steps

Into a 50-mL round-bottom flask, was placed a solution of methyl 3-(azepan-1-yl)-2-phenylquinoxaline-6-carboxylate (132.4 mg, 0.37 mmol, 1.00 equiv) in methanol (15 mL), a solution of sodium hydroxide (73.4 mg, 1.83 mmol, 5.00 equiv) in water (2 mL). The resulting solution was stirred overnight at 50° C. in an oil bath. The pH value of the solution was adjusted to 3-4 with 1N hydrogen chloride. The resulting mixture was concentrated under vacuum. The resulting mixture was washed with methanol. This resulted in 80 mg (61%) of 3-(azepan-1-yl)-2-phenylquinoxaline-6-carboxylic acid as a yellow solid.
