Reaction Steps

3-Pyridazineacetic acid is esterified with anhydrous ethanolic hydrogen chloride and the resulting ethyl ester is reduced with lithium aluminium hydride in tetrahydrofuran to give 3-(2-hydroxyethyl)pyridazine. Treating this hydroxyethyl compound with thionyl chloride gives 3-(2-chloroethyl)pyridazine.
