Procedure

To N-tert-butyl-3-{6-[4-methyl-6-(6-trifluoromethyl-pyridin-3-yl)-pyrimidin-2-yl]-pyridin-2-yl}-benzenesulfonamide (Example 26) (0.092 g, 0.174 mmol) was added TFA (2 mL) and the reaction mixture was stirred at 23° C. for 16 h. The mixture was partitioned between EtOAc and saturated NaHCO3 solution, the organic layer was dried over Na2SO4. Removal of the solvent in vacuum left a crude product which was triturated with diethyl ether to give the title compound as an off-white solid (0.080 g, 98%). MS (ISP) 472.0 [(M+H)+]; mp 254° C.
