Reaction Steps

To a solution of ethyl 2-(2-oxopyrrolidin-1-yl)benzoate (4.3 g) in methanol (30 mL) was added 8 N aqueous sodium hydroxide solution (6.9 mL) at room temperature, and the mixture was heated to 50° C., and stirred overnight. The reaction mixture was allowed to cool to room temperature, and neutralized with 6 N aqueous hydrochloric acid solution (3 mL), and the solvent was evaporated under reduced pressure. The resultant crystals were recrystallized from ethanol to give the title compound (2.58 g).
