실험 절차

To a cooled and stirred solution of 5-{1-[4-(3-methyl-4-trifluoromethyl-phenyl)-6-trifluoromethyl-pyrimidin-2-yl]-1H-imidazol-4-yl}-thiophene-2-sulfonic acid tert-butyl amide (0.24 g) in dichloromethane (5 mL) was added TFA (5 mL) and the reaction mixture was allowed to stir at room temperature for 15 h. The mixture was evaporated to dryness and purified by column chromatography on silica gel (dichloromethane/MeOH/NH4OH 80:10:1) and crystallization (MeOH/diethyl ether) to yield the title compound as a light yellow solid (0.14 g, 52%). MS (ISN) 532.3 [(M−H)−]; mp 260° C.
