Participants

Reaction Steps

HOBT (65 mg) and EDC (92 mg) were sequentially added to a solution of 5-(4-fluorophenyl)-2-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-1H-imidazole-4-carboxylic acid (100 mg), 2-chloroethylamine hydrochloride (56 mg) and IPEA (0.25 mL) in DMF (3 mL). The reaction solution was stirred at room temperature for two hours. Then, 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 (carrier: Chromatorex™ NH; elution solvent: ethyl acetate→ethyl acetate:methanol=5:1) to obtain 19 mg of the title compound. The property values of the compound are as follows.
