Reaction Steps

To N-tert-butyl-3-{6-[4-methyl-6-(4-trifluoromethyl-phenyl)-pyrimidin-2-yl]-pyridin-2-yl}-benzenesulfonamide (Example 436) (0.100 g, 0.185 mmol) was added TFA (3 mL) and the reaction mixture was stirred at 23° C. for 3 h. The mixture was partitioned between EtOAc and saturated NaHCO3 solution, the organic layer was dried over MgSO4. 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 (0.068 g, 76%). MS (ISP) 486.0 [(M+H)+]; mp 231° C. (dec.).
