Reaction Steps
Into a 50-mL round-bottom flask, was placed a solution of (R)-methyl 3-(2-methylpyrrolidin-1-yl)-2-phenylquinoxaline-6-carboxylate (178 mg, 0.51 mmol, 1.00 equiv) in methanol (15 mL). A solution of sodium hydroxide (102.6 mg, 2.56 mmol, 5.00 equiv) in water (1.5 mL) was added. The resulting solution was stirred overnight at 50° C. in an oil bath and concentrated to dryness. The residue and diluted by 10 ml of water and pH value of the aqueous solution was adjusted to pH=3-4 with 1N hydrogen chloride. The resulting solid was collected by filtration as product. This resulted in 130 mg (75%) of (R)-3-(2-methylpyrrolidin-1-yl)-2-phenylquinoxaline-6-carboxylic acid as a yellow solid.
