Procedure

3-{[Bis(benzyloxy)phosphoryl]oxy}propyl 1-ethyl-6-{6-[(ethylcarbamoyl)amino]-4-[4-(trifluoromethyl)-1,3-thiazol-2-yl]pyridin-3-yl}-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate (Example 21, 700 mg, 0.82 mM) was dissolved in dry dichloromethane (40 mL), and the reaction mixture was cooled to 0° C. Trimethylsilyl bromide (251 mg, 1.64 mmol) was added and the mixture was stirred for 16 h at room temperature. A solid formed on the walls of round bottom flask. The solvent was decanted and the solid was washed with ethyl acetate (30 mL) to give crude compound. The crude compound was dissolved in methanol (20 mL) and water (30 mL) was added to precipitate the product which was filtered and dried to afford 230 mg (35%) of 3-(phosphonooxy)propyl 1-ethyl-6-{6-[(ethylcarbamoyl)amino]-4-[4-(trifluoromethyl)-1,3-thiazol-2-yl]pyridin-3-yl}-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate.
