Reaction Steps

A mixture of 14.9 g 3,6-dichloro-pyridazine, 10.45 g 4-chlorophenol and 13.8 g potassium carbonate is maintained for half an hour at 160° C., and then poured into an aqueous dilute sodium hydroxide solution. The precipitate which appears in isolated and recrystallised from an aromatic solvent. There is thus obtained, at 70% yield, 3-chloro-6-(4-chlorophenoxy)-pyridazine which melts at 119° C.
