General description
Products of reaction of methyl iodide with 4-methylpyridazine has been investigated by NMR spectra. Solvent free oxidation of 4-methylpyridazine by acetyl peroxyborate, peracetic acid and hydrogen peroxide has been reported.
Application
4-Methylpyridazine was used in the preparation of series of novel pyridazine derivatives structurally related to bipyridine cardiotonics.

Preparation of a series of novel pyridazine derivatives structurally related to bipyridine cardiotonics, starting from 4-methylpyridazine or 4-acetylpyridazine, respectively, is described. As observed with compounds 8, 11 and 16, an enhancement of in vitro cardiotonic activity is associated with the
