Reaction Steps

To a r.b. flask was added 3,5-dichloro-4,5-bis(4-chlorophenyl)pyridazine (4.5 gm, 12.2 mmol), pyridine (20 ml) and hydrazine monohydrate (1.494 gm, 30.49 mmol). The reaction mixture was stirred at 120° C. for 1 h. After this time, the reaction mixture was cooled to RT Water (400 ml) was then added and a solid precipitated. The solution was filtered and the solid was collected and air dried overnight to give the title compound, 1-(6-chloro-4,5-bis(4-chlorophenyl)pyridazin-3-yl)hydrazine (3.7 gm, 83% yield) as a solid. MS (M+H)=364.9.
