Participants

Reaction Steps

To a solution of (E)-3-[4-({5-[(4-fluorobenzyl)oxy]pyridin-2-yl}oxy)-3,5-dimethylphenyl]-1-(piperazin-1-yl)prop-2-en-1-one (0.328 g) and (E)-3-[4-(chloromethyl)-2-methylphenyl]prop-2-en-1-yl 4-methylphenyl ether (0.204 g) in DMF (2 mL) was added DIPEA (0.13 mL) at room temperature under an Ar atmosphere. The mixture was stirred at room temperature for 20.5 hours, and then heated at 50° C. for 1 hour, and then cooled to room temperature, and evaporated under reduced pressure. To the residue was added saturated aqueous NaHCO3, and the mixture was extracted with AcOEt. The organic layer was washed with saturated aqueous NaCl, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (AcOEt) to afford (2E)-3-[4-({5-[(4-fluorobenzyl)oxy]pyridin-2-yl}oxy)-3,5-dimethylphenyl]-1-(4-{3-methyl-4-[(1E)-3-(4-methylphenoxy)prop-1-en-1-yl]benzyl}piperazin-1-yl)prop-2-en-1-one (0.370 g) as a colorless oil.
