Versuchsvorschrift

To a cooled and stirred solution of 5-{4-[4-trifluoromethyl-6-(4-trifluoromethylphenyl)-pyrimidin-2-yl]-pyridin-2-yl}-thiophene-2-sulfonic acid tert-butylamide (example 162) (0.2 g, 0.34 mmol) in dichloromethane (3 mL) was added TFA (3 mL) and the reaction mixture was allowed to stir at room temperature for 15 h. The mixture was evaporated to dryness and purified by flash chromatography (heptane/ethyl acetate) to yield the title compound as an off-white solid (0.12 g, 67%). MS (ISN) 529.3 [(M−H)−]; mp 262° C.
