86%	Stage #1: 7-fluoro-2-methoxy-1,5-naphthyridine With hydrogen bromide; acetic acid at 20℃; for 18h; Stage #2: With water; sodium hydrogencarbonate at 20℃; for 1h;	7.b (b) .7-Fluoro- 1 , 5 -naphthyridin-2( 1 H)-one; A suspension of 7-fluoro-2-(methoxy)-l,5-naphthyridine (3.044g, 17.101mmol) in glacial acetic acid (50ml) at rt under argon, was treated with 33% HBr in acetic acid (50ml). After stirring at rt for 18 h, the solvents were evaporated (copious fumes of HBr were produced). The residue was treated with acetic acid (100ml) and re-evaporated, then stirred with water (200ml) and the pH of the suspension was adjusted to pH 4 by addition of solid sodium hydrogen carbonate. The mixture was then stirred at rt for 1 hour then the solid was isolated by filtration with suction to give an off-white damp solid. The product was dried on the sinter with suction for 2 hours then dried in a vacuum desiccator over P2O5 overnight to give the desired compound as a white solid (2.412g, 86%). MS (ES+) m/z 165 (MH+).

This reaction mixture was purged for 5 min with argon followed by the addition of Pd(OAc)2 (0.061 g, 0.273 mmol). The reaction mixture was heated at 150C for 4h (monitored by TLC & LCMS for completion), and the reaction mixture was filtered through celite bed and solvent was evaporated under reduced pressure. The reaction mixture was further extracted with ethyl acetate (3×40mL). The combined organic extracts were washed with brine (2 × 40 mL) and water (3 × 50 mL), dried (MgSO4) and concentrated under reduced pressure. The crude residue was purified by silica gel column chromatography using hexane: ethyl acetate as eluent to give 7-fluoro-1, 5-naphthyridin-2(1H)-one (6) (1.23 g, 53 %) as brown solid.
