A mixture of 6(3-chloro-4-fluorobenzyl)-4-methoxy-3,5-dioxo-2,3,5,6,7,8-hexahydro-2,6-naphthyridine-1-carboxylic acid (0.19 g, 0.49 mmol), N-[2-(benzyloxy)-ethyl]-4-{[tert-butyl(dimethyl)silyl]oxy}butan-1-amine (0.19 g, 0.55 mmol), EDC (0.10 g, 0.55 mmol), HOAt (75 mg, 0.55 mmol) and diisopropylethylamine (0.35 mL, 1.99 mmol) in DMF (2 mL) was stirred at room temperature overnight. The product mixture was concentrated under vacuum. The residue was partitioned between methylene chloride and water. The organic extract was dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum to afford the title compound. This material was used in the following step without further purification.
