In 20 ml of ethyl acetate were dissolved 557 mg (1.05 mmol) of (2R,3R)-2-(2,4-difluorophenyl)-3-(1H-1,2,4-triazol-1-yl)-3-[[1-(tert-butoxycarbonyl)piperidin-4-yl]thio]-2-butanol, and 2.63 ml (10.5 mmol) of a 4N hydrogen chloride-ethyl acetate solution were added to the solution, followed by stirring of the resulting mixture at 40° C. for 8 hours. After cooling, the precipitated solid was collected by filtration and washed with hexane to obtain 460 mg (yield: 100%) of the desired compound as a colorless powder.
