Reaction Steps
To mixture of 0.3 g (2-{(E)-3-[1-(4-Iodo-benzenesulfonyl)-1H-pyrrol-3-yl]-allanoylamino}-phenyl)-carbamic acid tert-butyl ester, 0.116 g 2-methoxy-5-pyridineboronic acid and 11 ml dimethoxyethane are added under an inert gas atmosphere 0.9 ml of an aqueous solution of 2N sodium sulfate and 70 mg of bis-(triphenylphosphine)palladium-(II)chloride. The mixture is refluxed for 24 h and after filtration and evaporation the residue is extracted between ethyl acetate and a 5% aqueous solution of sodium bicarbonate. The organic phase is dried and evaporated and th4e crude product is purified by silica gel flash chromatography. 87% of a colorless solid are obtained.
