3,4-Diaminopyridazine has been shown to condense with benzil, diacetyl and phenylglyoxal to give 6,7-diphenyl-, 6,7-dimethyl- and 6(7)-phenyl-pyrazinopyridazine, respectively.Syntheses of 2-, 5-, and 7-methyl-6-methylthioimidazopyridazine have been described.Methylation of 6-mercaptoimidazopyridazine with diazomethane gave 1- and 7-methyl-6-methylthioimidazopyridazine but methyl iodide gave 1- and 2-methyl-6-methylthioimidazopyridazine.Diazomethane methylation of 6-hydroxyimidazopyridazine gave three dimethyl derivatives of which one was identified as 6-methoxy-1-methylimidazopyridazine.
