実験手順

A mixture of 4.5 parts of 3-chloro-6-(1H-imidazol-1-yl)pyridazine, 3.2 parts of 4-bromophenol, 4.2 parts of sodium carbonate and 80 parts of 2-propanone was stirred and refluxed over weekend. The reaction mixture was evaporated and the residue was taken up in water and 2,2'-oxybispropane. The layers were separated. The organic phase was dried, filtered and evaporated. The residue was crystallized from 2-propanol, yielding 3.5 parts of 3-(4-bromophenoxy)-6-(1H-imidazol-1-yl)pyridazine; mp. 168.4° C. (compound 6).
