Reaction Steps

1-(3-Aminophenyl)-3-[3-(pyridin-4-yl)propyl]-1,8-naphthyridin-2(1H)-one (100 mg, 0.28 mmol; prepared in Synthetic Example 7) was heated in acetic anhydride (0.5 ml) and pyridine (0.5 ml) at 100° C. for 20 min, concentrated, neutralized with saturated aqueous sodium hydrogen carbonate, and extracted with chloroform. The extract was treated according to conventional techniques. Recrystallization from DMF yielded 1-(3-acetylaminophenyl)-3-[3-(pyridin-4-yl)propyl]-1,8-naphthyridin-2(1H)-one (91.3 mg, 82%; mp 200–202° C./DMF).
