Diisopropylethylamine → 5-chloro-2-(3,4,5-trifluorophenyl)pentanoic acid N'-{(E)-3-[3-fluoro-4-(4-methyl-1H-imidazol-1-yl)phenyl]acryloyl}hydrazide

Participants

Reaction Steps

IPEA (0.14 mL) and BOPCl (100 mg) were added to a solution of 5-chloro-2-(3,4,5-trifluorophenyl)pentanoic acid hydrazide hydrochloride (83 mg) and (E)-3-[3-fluoro-4-(4-methyl-1H-imidazol-1-yl)phenyl]acrylic acid (CAS No. 870839-63-7, 65 mg) in methylene chloride (5 mL), and the reaction solution was stirred at room temperature for 18 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: heptane:ethyl acetate=1:1→ethyl acetate→ethyl acetate:methanol=9:1) to obtain 103 mg of the title compound. The property value of the compound is as follows.
