Reaction Steps

Into a 50-mL round-bottom flask, was placed a solution of methyl 3-(4-methyl-1,4-diazepan-1-yl)-2-phenylquinoxaline-6-carboxylate (126.6 mg, 0.34 mmol, 1.00 equiv) in methanol (12 mL), a solution of sodium hydroxide (72.6 mg, 1.81 mmol, 5.00 equiv) in water (2.5 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 sent for prop-HPLC. This resulted in 46 mg (38%) of 3-(4-methyl-1,4-diazepan-1-yl)-2-phenylquinoxaline-6-carboxylic acid as a yellow solid.
