Reaction Steps

To 100 mg of 3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butanenitrile were added 0.2 ml of diethyl dithiophosphate and 0.04 ml of water. The resulting mixture was subjected to reaction at 80°-90° C. for 5hours. The reaction mixture was purified by a column chromatography (eluant: chloroform/methanol=50/1) to obtain an oily matter. To the oily matter was added 0.5 ml of a 2N hydrochloric acid-dioxane solution, and then diethyl ether was added. The resulting crystals were collected by filtration to obtain 110 mg of 3-(2,4-difluorophenyl)-2,2-difluoro-3-hydroxy-4-(1H-1,2,4-triazol-1yl)butanethioamide hydrochloride.
