Abstract: | While reduction of ethylpyridazine-4-carboxylate (1 b) by LiAlH4 or NaBH4 yields mixtures of 4-hydroxymethyl-pyridazine (1 a) and ethyl-2.5-dihydro-pyridazine-4-carboxylate (2), pyridazine-4-carbaldehyde and 4-acetyl-pyridazine quantitatively by NaBH4 are reduced to the corresponding carbinols1 a, 1 d. 4-Chloromethyl-pyridazine easily can be prepared by reaction of1 a with SOCl2. The structures of the new compounds are proved by1H-NMR-, IR- and mass-spectroscopy.
