Reaction Steps

To a previously degassed mixture of (3-[(5-bromo-furan-2-carbonyl)-amino]-phenyl)-acetic acid ethyl ester (11)(0.4 g), 4-(dimethylamino)phenylboronic acid (0.23 g), potassium carbonate (0.39 g) and tetra-n-butylammonium bromide (0.37 g) in water (2 ml) was added palladium II acetate (circa 10 mg). The mixture was heated to 70° C. for an hour, cooled and partitioned between ethyl acetate and water. The organic layer was separated, washed with brine, dried over sodium sulphate and evaporated in vacuo. Compound 13(0.33 g) was obtained following silica gel column chromatography of the residue in 2:3 ethyl acetate:petroleum ether.
