The synthesis and properties of several 1,4‐dimethylpyridazino[4,5‐ d ]pyridazines are described. Treatment of diethyl 3,6‐dimethylpyridazine‐4,5‐dicarboxylate ( 1a ) with lithium aluminium hydride and hydrazine did not afford the expected 1,4‐dimethylpyridazino[4,5‐ d ]pyridazine ( 21b ) but a mixture of compounds 13, 18, 19 , and 20 , whose structures were deduced from spectroscopic data.
