Procedure

A solution of 5-chloro-2-(3,4,5-trifluorophenyl)pentanoic acid N′-{(Z)-2-fluoro-3-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]acryloyl}hydrazide (84 mg) in phosphorus oxychloride (1 mL) was stirred at 120° C. for 7.5 hours. The reaction solution was left to cool to room temperature and then concentrated under reduced pressure to obtain 81 mg of the title compound. The property value of the compound is as follows.
