Procedure:
Phosphorus oxychloride (3.4 mL, 30 mmol) was added to chilled (ice bath) N,N-dimethylformamide (15 mL). The resulting solution was added dropwise to a solution of 3-nitro[1,5]naphthyridin-4-ol (5.73 g, 30 mmol) in N,N-dimethylformamide (35 mL). The reaction mixture was maintained at ambient temperature for 5 hours and then it was poured onto ice. The resulting yellow precipitate was isolated by filtration and then partitioned between dichloromethane (200 mL) and water (150 mL). The organic layer was separated, dried over magnesium sulfate, filtered, and then concentrated under vacuum to provide 4.2 g of crude 4-chloro-3-nitro[1,5]naphthyridine.

Procedure:
A slurry of 11.6 g (0.1 mole) fumaric acid was dissolved in 30 ml water was mixed with 26 g of 30% aqueous solution of ammonium hydroxide (0.22 mol NH3). Carefully warming the slurry to boiling gave a clear solution. This solution was boiled to dryness over a period of 15 minutes to give a white crystalline solid. The solid was tumbled under nitrogen at 100 Torr, at 235°-245° C. for 1.5 hours to give a water insoluble, brown, glasslike solid weighing 9.0 g. This solid was dissolved in 100 g of an aqueous solution containing 2.0 g of sodium hydroxide to form a pale yellow solution, pH 8.5, containing 25% solids.

Procedure:
Into 20 mL of methylene chloride, 0.250 g of the naphthyl acetic acid prepared as in Example 2 above, was dissolved. After cooling the solution in an ice bath, 0.090 mL of oxalyl chloride and a few drops of dimethylformamide were added. After 30 minutes, the ice bath was removed, and the reaction was allowed to come to room temperature over 30 minutes. The solvent of the reaction mixture was removed under vacuum, and product was redissolved in 50 mL of methylene chloride, followed by evaporation under vacuum, giving the napthylacetyl chloride as an oil. This product was redissolved in 40 mL of methylene chloride, and excess ammonia was bubbled in over 15 minutes at room temperature. After stirring overnight, the solvent of the reaction mixture was removed under vacuum. The reaction product was redissolved in ethyl acetate and washed with brine and dilute potassium carbonate. The organic solution was dried over sodium sulfate, and filtered. The solvent was removed under vacuum, and the product was redissolved in a minimum of methylene chloride. On dilution to cloudiness with hexane and after cooling, 130 mg (55%) of 4-phenoxynaphth-1-yl-acetamide was obtained.
