실험 절차

To a cooled and stirred solution of N-tert-butyl-3-{1-[6-(3,4-difluoro-phenyl)-4-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-benzenesulfonamide (0.16 g) in dichloromethane (4 ml) was added TFA (4 ml) and the reaction mixture was allowed to stir at room temperature for 15 h. The mixture was evaporated to dryness, poured into 2N NaHCO3 solution (20 ml) and extracted with ethyl acetate (3×50 ml). The combined organic layers were washed with brine (50 ml), dried (MgSO4) and evaporated. Further purification by flash chromatography on silica gel (dichloromethane/MeOH) and crystallization (ethyl acetate/heptane) yielded the title compound as a white solid (0.019 g, 12%). MS (ISP) 482.1 [(M+H)+]; mp 241.5° C.
