Abstract
4-X-3-(methoxymethyl)-6-methylpyridazine (X = Cl, Br, I) on treatment with potassium amide in liquid ammonia at − 33°C gives a mixture of 4- and 5-amino-3-(methoxymethyl)-6-methylpyridazine (ratio 1: 5), which ratio is independent of the nature of the halogen atom. A 4,5-didehydropyridazine is proposed as intermediate.
