Reaction Steps

In an analogous manner, from 0.6 g. 3-(5-nitro-2-furyl)-6-(ethoxy-methylene)-amino-s-triazolo[4,3-b]pyridazine in 12 ml. anhydrous dioxan and an ethanolic solution of hydroxylamine (prepared from 0.6 g. hydroxylamine hydrochloride in 15 ml. absolute ethanol by adding 0.14 g. sodium, dissolved in 5 ml. absolute ethanol, and filtering off with suction the precipitated sodium chloride) at 50° - 60°C., there was obtained, after a reaction period of 15 minutes and cooling of the reaction mixture, 0.55 g. 3-(5-nitro-2-furyl)-6-(hydroxylaminomethylene)-amino-s-triazolo[4,3-b]pyridazine, which melted, with foaming, at 251° - 253°C.
