Procedure

Anhydrous THF (12 liters) and dimethyl 5-hydroxy-isophthalate (2100 g) were combined under nitrogen in an oil jacketed 22 liter RB flask equipped with a condenser, mechanical stirrer, pressure equalizing addition funnel. To this stirred solution was added anhydrous potassium carbonate (1035 g), followed by 1,1,1,2,2,3,3-heptafluoro-3-(1,2,2-trifluorovinyloxy)propane (3192 g). Ca. 2 liters of additional THF was used to wash all the reagents into the reaction vessel. The resulting mixture was refluxed for 10.5 hours.
