Reaction Steps

To a solution of (E)-3-{3-chloro-5-methyl-4-[(5-{[4-(trifluoromethyl)benzyl]-oxy}pyridin-2-yl)oxy]phenyl}prop-2-enoic acid (139 mg) and 4-{2-[4-(piperazin-1-ylmethyl)-phenyl]ethoxy}benzonitrile trifluoroacetate (131 mg) in DMF (6 mL) was added DEPC (0.073 mL) and Et3N (0.165 mL) at 0° C. After stirring at 0° C. for 1 hour, to the reaction mixture was added H2O, and extracted with AcOEt. The organic layer was washed with saturated aqueous NaCl, dried over anhydrous MgSO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (AcOEt) to give 4-{2-[4-({4-[(E)-3-{3-chloro-5-methyl-4-[(5-{[4-(trifluoromethyl)benzyl]oxy}pyridin-2-yl)oxy]phenyl}prop-2-enoyl]piperazin-1-yl}methyl)phenyl]ethoxy}benzonitrile as a pale yellow amorphous (195 mg).
