A solution of [11-(3-chloro-4-fluorobenzyl)-9-hydroxy-1,8,10-trioxo-1,3,4,5,6,8,10,11,12,13-deca-hydro-2H-[1,4]diazocino[2,1-a]-2,6-naphthyridin-2-yl]acetic acid (25 mg, 0.05 mmol), BOP (28 mg, 0.06 mmol), diisopropylethylamine (7 mg, 0.07 mmol) and dimethylamine (0.11 mL, 2M in THF) in DMF (0.5 mL) was stirred at room temperature overnight. The product mixture was concentrated under vacuum. The residue was subjected to reverse phase column chromatography on C-18 stationary phase eluted with a 95-5% water-acetonitrile gradient. Collection and lyophilization of appropriate fractions afforded the title compound.
