Procedure

The title compound was prepared according to the general procedure for the synthesis of heterocyclyl and heteroaryl substituted phenylsulfonyl derivatives previously described, using 4-Bromo-N-[4-chloro-2-(pyridine-4-carbonyl)-phenyl]-benzenesulfonamide 0.3 g (0.66 mmol), potassium phosphate tribasic monohydrate 0.91 g (3.96 mmol), rac-2,2′-bis (diphenylphosphino)-1,1′-binaphthyl 0.12 g (0.198 mmol), piperidine 0.28 g (3.3 mmol) and Pd (dba)3 60 mg (0.066 mmol) in 6 ml dioxane. The crude reaction mixture was purified using HPLC to yield the title compound as a yellow solid.
