Reaction Steps

A mixture of 191 mg (0.5 mmole) 4-(2-bromo-6-pyrrolidine-1-yl-pyridine-4-sulfonyl)-phenylamine, 84 mg (0.55 mmole) 4-tolylboronic acid, 18 mg bis(triphenylphosphine)-palladium(II)-chloride is refluxed for 2.5 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 80 mg (40%) pure 4-(2-pyrrolidine-1-yl-6-p-tolyl-pyridine-4-sulfonyl)-phenylamine as a pale yellow solid mp.: 250-251° C.
