To a suspension of (E)-5-chloro-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl]benzylidene)valeric acid ethyl ester (200 mg) obtained in Example 417 and 2-(aminomethyl)-6-chloropyridine (CA 188637-75-4) hydrochloride (100 mg) in ethanol (3 mL) and DMF (3 mL), anhydrous potassium carbonate (100 mg) was added and the reaction mixture was agitated at 100° C. for 8 hours. After the reaction mixture was allowed to be cooled to room temperature, the reaction mixture was poured into iced water and the reaction solution was extracted with ethyl acetate. The obtained organic layer was washed with a saturated sodium chloride solution, and concentrated under reduced pressure after dried over anhydrous magnesium sulfate. Ethanol (10 mL) and sodium hydroxide (1.0 g) aqueous solution (5 mL) were added to the residue, and the reaction solution was agitated at room temperature for 1 hour. The reaction solution was added to iced water and the reaction solution was extracted with ethyl acetate. The obtained organic layer was washed with a saturated sodium chloride solution, and it concentrated under reduced pressure after dried over anhydrous magnesium sulfate. 23 mg of the title compound was obtained by the residue was purified by silica gel chromatography (elution solvent: heptane-ethyl acetate system).
