实验步骤: There was dissolved 17.59 g (70 mmol) of (2R,3S)-2-(2,4-difluorophenyl)-3-methyl-2-[(1H-1,2,4-triazol-1-yl)methyl]oxirane in 113 g of an aqueous solution of 4-methylenepiperidine (content: 61%) and the obtained solution was refluxed with heating at 90° C. for 21 hours. After the reaction, an excess of 4-methylenepiperidine was removed under reduced pressure, and the residue was dissolved in 140 ml of isopropyl alcohol and thereto was added 13.32 g (70 mmol) of p-toluenesulfonic acid monohydrate dissolved in 50 ml of isopropyl alcohol. The obtained mixture was allowed to stand for 1 hour at room temperature and overnight in a refrigerator, and then the precipitated crystal was separated by filtration and washed with 50 ml of isopropyl alcohol and dried to obtain 32.20 g of (2R,3R)-2-(2,4-difluorophenyl)-3-(4-methylenepiperidino)-1-(1H-1,2,4-triazol-1-yl)butan-2-ol p-toluenesulfonate in a form of a crystal. the obtained solution was refluxed After the reaction an excess of 4-methylenepiperidine was removed under reduced pressure the residue was dissolved in 140 ml of isopropyl alcohol the precipitated crystal was separated by filtration washed with 50 ml of isopropyl alcohol dried
