实验步骤: To a DMF (5 mL) solution of (E)-3-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)acrylic acid (60 mg) obtained in Example 121, 1-(4-fluorophenyl)-1-methylethylamine (CAS#17797-10-3) (43 mg), EDC (53 mg) and HOBT (38 mg) were added at room temperature under nitrogen atmosphere, and the reaction solution was agitated at room temperature for 12 hours. Water and ethyl acetate were added to the reaction solution, and the organic layer was partitioned. The organic layer was washed with a saturated sodium chloride solution, and the organic layer was concentrated under reduced pressure after dried over anhydrous magnesium sulfate. The obtained residue was purified by silica gel chromatography (elution solvent: methanol-ethyl acetate system), and the title compound (60 mg) was obtained. the organic layer was partitioned The organic layer was washed with a saturated sodium chloride solution the organic layer was concentrated under reduced pressure after dried over anhydrous magnesium sulfate The obtained residue was purified by silica gel chromatography (elution solvent: methanol-ethyl acetate system)
