Procedure

IPEA (0.5 mL), HOBT (128 mg) and EDC (182 mg) were added to a solution of 5-chloro-2-{1-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]-(E)-methylidene}valeric acid hydrazide dihydrochloride (200 mg) and 4-fluorophenylacetic acid (73 mg) in DMF (3 mL), and the reaction solution was stirred at room temperature for six hours. Ethyl acetate and saturated sodium bicarbonate water were added to the reaction solution, 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 75 mg of 2-(4-fluorophenyl)-N-{3-{1-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]-(E)-methylidene}-2-oxopiperidin-1-yl}acetamide and 217 mg of (4-fluorophenyl)acetic acid N′-{5-chloro-2-{1-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]-(E)-methylidene}pentanoyl}hydrazide.
