Reaction Steps

To a CH2Cl2 (5 mL) solution of (E)-3-[3-chloro-5-methyl-4-({5-[(4-methylbenzyl)oxy]pyridin-2-yl}oxy)phenyl]-1-[(3S)-3-methylpiperazin-1-yl]prop-2-en-1-one (0.50 g) and 4-[2-(4-fluorophenoxy)ethyl]benzaldehyde (298 mg) was added NaBH(OAc)3 (323 mg) at room temperature. The resultant mixture was stirred at room temperature for 3 days. To the reaction mixture was added saturated aqueous NaHCO3, and extracted with CH2Cl2. 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 (n-hexane/AcOEt=1/1 to 0/1) to give (E)-3-[3-chloro-5-methyl-4-({5-[(4-methylbenzyl)oxy]pyridin-2-yl}oxy)phenyl]-1-[(3S)-4-{4-[2-(4-fluorophenoxy)ethyl]benzyl}-3-methylpiperazin-1-yl]prop-2-en-1-one as a yellow powder (451 mg).
