PROCEDURE
实验过程
The mixture of 2,3-difluoro-4-nitrophenylacetic acid and 2,3-difluoro-6-nitrophenylacetic acid from D16 (13.5 g) was dissolved in dimethylformamide (100 ml) and potassium carbonate (8.5 g) added. After stirring at 50° C. for 30 min the cooled solution was partitioned between aqueous hydrochloric acid and hexane. Drying (MgSO4), evaporation, and chromatography (0-5% ethyl acetate in hexane, 70 g silica column) gave 3.2 g of a 3:1 mixture of the title compound and 2,3-difluoro-6-nitrotoluene.
