Procedure

To a solution of 5-(3-amino-cyclohexyl)-9-chloro-3-methyl-5H-isoxazolo[4,3-c]quinolin-4-one hydroiodide, 130 mg (0.28 mmol) in 10 mL of DMF was added 82 mg (0.28 mmol) of (benzenesulfonyl-pyridin-2-yl-amino)-acetic acid (Bionet), 46 mg (0.34 mmol) of 1-hydroxy-7-azabenzo-triazole, 66 mg (0.34 mmol) of EDC, 5 mg of DMAP and 120 μL (0.84 mmol) of TEA. The reaction mixture was stirred six days at rt. and was concentrated to dryness. The residue was dissolved in 20% isopropanol/chloroform, washed with saturated NaHCO3, washed with brine, dried over Na2SO4, filtered and concentrated to dryness. The residue was purified by radial chromatography using a MeOH/chloroform gradient and concentrated to dryness. The residue was slurried in ether/hexanes and concentrated to dryness to yield 79 mg (47%) of the title compound as a tan foam. MS (ion spray) 606.1 (M+).
