실험 절차

A solution of 3-fluorobenzoic acid N′-{(E)-3-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]acryloyl}hydrazide (86 mg) in phosphorus oxychloride (2 mL) was stirred at 120° C. for one hour. The reaction solution was left to cool to room temperature and concentrated under reduced pressure. Methylene chloride and a 1 N sodium hydroxide solution 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 (carrier: Chromatorex™ NH; elution solvent: heptane:ethyl acetate=1:1->ethyl acetate) to obtain 65 mg of the title compound. The property values of the compound are as follows.
