実験手順

To a stirred and cooled solution of N-tert-butyl-3-[4-trifluoromethyl-6-(4-trifluoromethyl-phenyl)-[2,4′]bipyridinyl-2′-yl]-benzenesulfonamide (example 285) (0.248 g, 0.43 mmol) in dichloromethane (3 mL) was added TFA (3 mL) and the reaction mixture was allowed to stir at room temperature for 16 h. The mixture was evaporated to dryness and saturated NaHCO3 solution (5 mL), diethyl ether and heptane were added. The mixture was stirred at room temperature for 1 h, the precipitate was collected by filtration, washed with water and heptane/diethyl ether and dried to yield the title compound as a white solid (0.182 g, 81%). MS (ISP) 524.3 [(M+H)+]; mp 227° C. (dec.).
