Procedure

A solution of 2-[1-(4-fluorophenyl)ethyl]-5-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-[1,3,4]oxadiazole (23 mg) and ammonium acetate (88 mg) in acetic acid (1 mL) was stirred at 150° C. for 10 hours. The reaction solution was left to cool to room temperature and concentrated under reduced pressure. Ethyl acetate and saturated sodium bicarbonate water were added to the residue, and the organic layer was separated. The resulting organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: ethyl acetate→ethyl acetate:methanol=5:1) to obtain 8 mg of the title compound. The property values of the compound are as follows.
