A mixture of 191 mg (0.5 mmole) 4-(2-bromo-6-pyrrolidine-1-yl-pyridine-4-sulfonyl)-phenylamine, 77 mg (0.55 mmole) 4-fluorophenylboronic acid, 18 mg bis(triphenylphosphine)-palladium(II)-chloride is refluxed for 2 hours in 7 ml toluene and 2 ml 2N aqueous potassium carbonate. The solvents are removed in vacuo. Flash chromatography (silicagel, ethyl acetate/hexane 1/1) of the residue yields 45 mg (22%) pure 4-[2-(4-fluoro-phenyl)-6-pyrrolidine-1-yl-pyridine-4-sulfonyl]-phenylamine as a white solid mp.: 245-246° C.
