Procedure
This compounds was synthesised in the same manner as described above. 3-(3,4-Dimethoxy-phenyl)-6-ethyl-7-hydroxy-chromen-4-one (0.25 g, 0.77 mmol), hydrazine hydrate (4 ml), ethanol (10 ml). The crude solid product was columned to give 4-[4-(3,4-Dimethoxy-phenyl)-1H-pyrazol-3-yl]-6-ethyl-benzene-1,3-diol as a white solid (0.16 g, 61.1%); Rf 0.33 Cf SM 0.71 ethyl acetate/hexane (75/25).
