Procedure
3-(4-Bromo-phenyl)-6-chloro-7-hydroxy-chromen-4-one (0.35 g, 1 mmol) and hexamethylene tetramine (0.14 g, 1 mmol) were dissolved in glacial acetic acid (20 ml) and heated overnight at 100° C. Warm 6M HCl (10 ml) was added and the mixture heated for a further hour before being poured in to water. The precipitate formed was filtered, washed and dried to provide the pure desired product as a pale brown solid.
