Procedure: 5.25 g (0.02 mol) of triphenyl phosphine was dissolved in 20 ml of dichloromethane, and the mixture was cooled to 0° C. 2.1 g (0.01 mol) of dibromodifluoromethane was added to the mixture using an injector, and the reaction mixture was stirred for 30 minutes at room temperature. 1.06 g (0.01 mol) of benzaldehyde was added thereto and the mixture was refluxed for 4 hours. The resulting mixture was distilled under a reduced pressure at 40° C./1 mmHg using a distilling apparatus to obtain the title compound (0.81 g, 57.5%). the mixture was refluxed for 4 hours The resulting mixture was distilled under a reduced pressure at 40° C./1 mmHg
