Reaction Steps
The preparation of 3-(5-nitro-2-furyl)-6-chloro-s-triazolo[4,3-b]pyridazine was carried out by the oxidative cyclization of 1-(5-nitro-furfurylidene)-2-(3-chloro-6-pyridazinyl) hydrazine (m.p. 250° - 254°C.) with lead tetraacetate. The yield was 79% and the product, after recrystallization from dimethyl formamide, melted at 222° - 226°C.
