実験手順
A solution of 10 g 3-chloro-6-(4-chlorophenoxy)-pyridazine in 100 ml acetic acid is maintained at reflux temperature for a few hours. The precipitate which appears on cooling is isolated and then recrystallised from butanol. There is thus obtained, at 80% yield, 6-(4-chlorophenoxy)-3-pyridazinone which melts at 202° C.
