Versuchsvorschrift

N-Cyclopropyl-N-piperidin-4-yl-3-trifluoromethyl-benzenesulfonamide (0.174 g, 0.50 mmol), HOBt (0.068 g, 0.50 mmol), EDCI (0.115 g, 0.60 mmol) and 6-hydroxynicotinoic acid (0.078 g, 0.55 mmol) were dissolved in 5 ml of dry DMF. The mixture allowed to stir at room temperature for 10 hours. The reaction mixture was concentrated and dried under reduced pressure. Then residue was dissolved in EtOAc (30 ml) and the mixture was washed with saturated NaHCO3 (15 ml) and brine (15 ml). The organic layer was dried over MgSO4 and concentrated to dryness. The crude product was purified through a column of silica gel with a gradient of 5% to 10% MeOH in CHCl3 to afford the title compound 6 (colorless solid, 195 mg, 83%). LC: 100%. MS: m/z=469.
