130 °C

A mixture of 49.5 g (0.175 mole) of bromo bis(4-fluoro phenyl)methane, 22.4 g (0.21 mole) of sodium carbonate and 26.9 g (0.21 mole) of 2-bromoethanol was stirred at 130° C. for 15 hours. After cooling, the reaction mixture was taken up with water and extracted with ether. The ethereal phase was washed, dried on sodium sulfate and then concentrated dry. Distillation of the residue yielded 41.9 g (yield: 69.4%) of 1-[bis(4-fluorophenyl) methoxy]-2-bromoethane.
