Procedure

To a solution of 4-[2-(1-tert-butoxycarbonyl-piperidin-2-yl)-ethoxy]-7-chloro-3-(3,5-dimethylphenyl)-2-oxo-1,2-dihydroquinoline-6-carboxylic acid (48 mg in 0.50 mL methylene chloride) was added 12 mg 1-hydroxybenzotriazole (HOBt) followed by 0.020 mL diisobutylamine, 0.025 mL triethylamine and 33 mg 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) and the mixture stirred at room temperature. After 22 hours, the mixture was diluted with methylene chloride and washed with 10% aqueous sodium bisulfate and brine. The organics were dried over sodium sulfate and the concentrate purified by flash chromatography on silica gel (chloroform:methanol, 97.5:2.5) to give the title compound (37 mg).
