Reaction Steps

To a DMF (7 mL) solution of (E)-3-[3-chloro-4-({5-[(2-chlorobenzyl)oxy]-pyridin-2-yl}oxy)-5-methylphenyl]-1-(piperazin-1-yl)prop-2-en-1-one (0.70 g) and 4-vinylbenzyl chloride (240 μL) was added K2CO3 (291 mg) at room temperature. After stirring at room temperature for 36 hours, to the reaction mixture was added water, and extracted with AcOEt. The organic layer was washed with water, saturated aqueous NaCl, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/AcOEt=1/1 to 0/1 and then AcOEt/MeOH=19/1) to give (E)-3-[3-chloro-4-({5-[(2-chlorobenzyl)oxy]pyridin-2-yl}oxy)-5-methylphenyl]-1-[4-(4-ethenylbenzyl)-piperazin-1-yl]prop-2-en-1-one as a colorless powder (0.73 g).
