Reaction Steps

[Step 4] 30 mg of the 4-oxo-2-methyl-2,3-dihydro-1H-[1,6]naphthyridine were dissolved in 2 mL of dichloromethane followed by adding 0.1 mL of triethylamine and 35 μL of acetic anhydride and stirring overnight at 40° C. Following completion of the reaction, the solution was concentrated under reduced pressure and the resulting residue was purified using silica gel chromatography (ethyl acetate) to obtain 7 mg of 1-acetyl-4-oxo-2-methyl-2,3-dihydro-1H-[1,6]naphthyridine in the form of a pale yellow oil (18%).
