실험 절차

The 13.8% toluene solution of 4-chloro-2'-nitrobutyrophenone obtained in Example 6 is treated, with stirring, first with 90 mL water and second with 50% NaOH (48 g, 0.6 mole NaOH). The resultant reaction mixture is allowed to exotherm, then is heated at 85°-90° C. for 2-3 hours, cooled to room temperature and allowed to settle. The phases are separated and the organic phase is washed with water. The aqueous phases are combined and washed with toluene. The organic phases are combined and concentrated in vacuo to give the title product as a toluene solution, 235 g, 23.6% title product by LC analysis (91% yield from furanone). The product solution is used as is in Example 8.
