실험 절차

To a stirred and cooled suspension of N-tert-butyl-3-{1-[6-trifluoromethyl-4-(4-trifluoromethyl-phenyl)-pyridin-2-yl]-1H-imidazol-4-yl}-benzenesulfonamide (example 293) (0.110 g, 0.19 mmol) in dichloromethane (0.69 mL) was added TFA (4.3 mL) and the reaction mixture was allowed to stir at room temperature for 16 h. The mixture was evaporated to dryness and saturated NaHCO3 solution (5 mL), diethyl ether and heptane were added. The mixture was stirred at room temperature for 1 h, the precipitate was collected by filtration, washed with water and heptane/diethyl ether and dried to yield after silica gel column chromatography with heptane/EtOAc and trituration with diethyl ether the title compound as a white solid (0.040 g, 40%). MS (ISP) 513.2 [(M+H)+]; mp>250° C.
