Procedure

To a solution of tert-butyl 4-(4-(4-hydroxy-4′-(trifluoromethyl)biphenyl-3-yl)pyridin-2-yl)piperazine-1-carboxylate (Preparation 114, 200 mg, 0.401 mmol) in dimethyl sulfoxide (5 mL) was added potassium carbonate (111 mg, 0.802 mmol) followed by 5-chloro-N-(2,4-dimethoxybenzyl)-2,4-difluoro-N-(pyrimidin-4-yl)benzenesulfonamide (Preparation 110, 182 mg, 0.401 mmol). The reaction mixture was stirred at room temperature for 2 hours and then partitioned between ethyl acetate (20 mL) and water (10 mL). The organic layer was separated, dried over anhydrous MgSO4, filtered and evaporated. The residue was purified by flash chromatography on silica gel eluting with 30% heptane in ethyl acetate to give the title compound (320 mg, 85%) as yellow foam.
