실험 절차

To the above prepared N-tert-butyl-3-{4-[4-methyl-6-(4-trifluoromethyl-phenyl)pyridin-2-yl]-pyrimidin-2-yl}-benzenesulfonamide (0.110 g, 0.19 mmol) was added TFA (6 mL) and the reaction mixture was stirred at 50° C. for 2 h. The mixture was evaporated to dryness and 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 a white solid (0.235 g, 100%). MS (ISP) 471.2 [(M+H)+]; mp>250° C.
