Reaction Steps

[Step 3] 2.2 g of the mixture of 1-(2-chloropyridin-3-yl)but-2-en-1-one and 1-(2-chloropyridin-3-yl)but-3-en-1-one and 4-methoxybenzylamine were dissolved in 30 mL of ethanol and stirred overnight at 70° C. Following completion of the reaction, the solution was concentrated under reduced pressure and water was added to the resulting residue followed by extracting three times with chloroform. After washing with saturated brine and dehydrating with anhydrous sodium sulfate, the solution was concentrated under reduced pressure and the resulting residue was purified using silica gel chromatography (ethyl acetate:hexane=1:3) to obtain 2.7 g of 1-(4-methoxybenzyl)-4-oxo-2-methyl-2,3-dihydro-1H-[1,8]-naphthyridine in the form of a yellow oil (80%).
