Procedure

Triphenylphosphine (22 mg) was added to a suspension of 3-(4-fluorophenyl)-3-methoxy-3-(5-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-2H-[1,2,4]triazol-3-yl)propan-1-ol (38 mg) in carbon tetrachloride (2 mL) and THF (2 mL), and the reaction solution was heated under reflux for seven hours. The reaction solution was left to cool to room temperature and concentrated under reduced pressure. Ethyl acetate and a saturated sodium bicarbonate solution were added to the resulting residue, and the organic layer was separated. The organic layer washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (carrier: Chromatorex™ NH; elution solvent: heptane-ethyl acetate system), again purified with silica gel column chromatography (elution solvent: ethyl acetate-methanol system) and then purified by LC-MS. After concentrating the target fraction, ethyl acetate and a saturated sodium bicarbonate solution were added to the residue, and the organic layer was separated. The organic layer washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 0.69 mg of the title compound. The property values of the compound are as follows.
