A mixture of 11.34 g (30 mmol) of 2-amino-5-bromo-3-iodobenzenesulphonic acid, 4.5 g (30 mmol) of 3-formylbenzeneboronic acid, 10.5 g (99 mmol) of sodium carbonate and 1.73 g (1.5 mmol) of tetrakis(triphenylphosphine)palladium (0) in 40 ml of dimethylformamide and 20 ml of water is heated at 70° C. under argon for 5 hours. The reaction medium is then concentrated under reduced pressure and the residue is purified by chromatography on an RP 18 column, eluting with a water-acetonitrile mixture (8:2).
