Procedure

To a solution of 2-(2,4-difluorophenyl)-1,1-difluoro-1-[(2-methoxyethyl)thio]-2,3-epoxypropane (13.0 g, 0.044 mol) in DMSO (100 ml), 1,2,4-triazole (7.6 g, 0.11 mol) and potassium carbonate (15.2 g, 0.11 mol) were added and the resulting mixture was stirred at room temperature for 12 hours and at an external temperature of 50° C. for one hour. After the completion of the reaction, the reaction mixture was diluted with ether and insoluble matter was filtered off. The ether solution was washed with water, dried over magnesium sulfate and distilled off under reduced pressure. The residue was recrystallized from isopropyl ether-ethyl acetate, whereby 2-(2,4-difluorophenyl)-1,1-difluoro-1-[(2-methoxyethyl)thio]-3-(1H-1,2,4-triazol-1-yl)-2-propanol (2.0 g, yield: 12.0%) was obtained as colorless crystals.
