실험 절차

157 g (1.4 mole or less) of CClF2CH(OH)2, 197 g (1.5 mole) of 2-bromoethanol and 20 g of calcium chloride were placed in a 1 liter-sized flask with a condenser. The flask was heated at 90° C. for 7 hours and cooled to room temperature. The upper phase was transferred to a 5 liter-sized flask, and 2 liters of acetone and 386 g (2.8 moles) of potassium carbonate were added to the flask. The mixture was reacted at 50° C. for three days, and a solid was precipitated. The solvent was removed by distillation. The product was purified by distillation. The yield of the product was 88% (195 g) and has a boiling point of 62° C./30 mmHg.
