To a DMF (5.0 mL) solution of (E)-5-chloro-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)valeric acid trifluoroacetic acid salt (3.0 g) obtained in Example 418 and 5-morpholin-4-yl-indan-1-ylamine (1.80 g), IPEA (5.18 mg), EDC (3.84 g) and HOBT (2.71 g) were added one by one, and the reaction solution was agitated at room temperature for 1 hour. After confirming disappearance of the starting materials, the solvent was concentrated under reduced pressure, water and ethyl acetate were added to the residue, and the organic layer was partitioned. After washed with a saturated saline solution the organic layer, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. 2.80 g of the title compound was obtained by purifying the obtained residue by silica gel chromatography (elution solvent:heptane-ethyl acetate system). The physical properties of the compound are as follows.
