Reaction Conditions

Reaction Steps

Concentrated hydrochloric acid (10 mL) was added to 1-(2,2-dimethoxy-2-pyridin-4-ylethyl)-3-{1-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]-(E)-methylidene}piperidin-2-one (580 mg), and the mixture was stirred at 50° C. for four hours. After confirming that the raw materials disappeared, the reaction solution was concentrated under reduced pressure. Saturated sodium bicarbonate water and ethyl acetate were added to the resulting residue, and the organic layer was separated. The resulting organic layer was washed with brine, and then dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (carrier: Chromatorex™ NH, elution solvent: heptane:ethyl acetate=1:2) to obtain 346.2 mg of the title compound. The property values of the compound are as follows.
