Procedure

This compounds was synthesised in the same manner as described above. 4-[4-(6-Chloro-7-hydroxy-4-oxo-4H-chromen-3-yl)-phenoxy]-butyronitrile (0.12 g, 0.34 mmol), Hydrazine hydrate (5 ml). The precipitate formed on quenching was filtered to give 4-{4-[3-(5-Chloro-2,4-dihydroxy-phenyl)-1H-pyrazol-4-yl]-phenoxy}-butyronitrile as a white solid (0.09 g, 71.6%); Rf 0.6 ethyl acetate/hexane (70/30)].
