실험 절차

6-[(4R)-4-{[3-(7-Methoxy-2-oxoquinoxalin-1(2H)-yl)propyl]amino}-2-oxopyrrolidin-1-yl]-2H-1,4-benzoxazin-3(4H)-one (2.86 g, 6.17 mmol) was dissolved in dichloromethane (50 ml) and ethanol (2 ml). To this solution was added 4 N hydrogen chloride/dioxane solution (1.59 ml, 6.37 mmol) under cooling in an ice bath. The precipitated insoluble material was collected by filtration and was then dried. The obtained residue was suspended in ethanol (20 ml), and the suspension was then stirred at 50° C. for 20 minutes. The suspension was cooled in an ice bath, and the insoluble material was collected by filtration. The filtrate was dried at 70° C. overnight under reduced pressure to yield 2.36 g (74%) of the above-captioned compound in the form of a colorless solid.
