Procedure
Dimethylformamide dimethylacetal (11.85 g) was added to a solution of 33.63 g ethyl 4-bromo-2,3,5,6-tetrafluorobenzoylacetate in 100 ml tetrahydrofuran cooled in an ice-bath. The reaction mixture was then immersed in a warm water bath in order to drive it to completion. The resulting solution was used directly in the next reaction.
