Procedure

464.5 g (1.95 mol) of 4-iodo-1,1,1-trifluorobutane, 390.4 g (1.95 mol) of 4-(benzyloxy)phenol and 539.5 g (3.90 mol) of potassium carbonate are dissolved in 3 L of NMP. The mixture is heated to 80° C. overnight. The solution is cooled to room temperature and the reaction mixture is extracted with ethyl acetate and water. The organic phase is washed repeatedly with water, dried over sodium sulfate, filtrated and concentrated under reduced pressure to give 580 g of
