Procedure

To a solution of 2-[[4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl]oxy]acetic acid (100 mg, 0.28 mmol) in dichloromethane (30 ml) was added EDAC.HCl (81 mg, 0.42 mmol), HOBt (57 mg, 0.42 mmol) and triethylamine (85 mg, 0.84 mmol). After 15 minutes 6-(trifluoromethyl)quinolin-2-amine (68 mg, 0.32 mmol) was added and the resulting solution was stirred overnight at room temperature. The contents were then quenched with water (100 ml) and extracted with dichloromethane (3×50 ml). The organic layers were combined and dried over anhydrous magnesium sulfate. The solids were filtered off and the filtrate was concentrated under vacuum to give a residue, which was purified by silica gel column chromatography using 3% methanol in dichloromethane to afford 2-[[4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl]-oxy]-N-[6-(trifluoromethyl)quinolin-2-yl]acetamide as a yellow solid (80.6 mg, 52%).
