Versuchsvorschrift

To a solution of the 7,8-bis(4-chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3(2H)-one, (800 mg, 2.24 mmol), prepared as described in Example 1, in 30 mL of DMF was added 2-(chloromethyl)phenyl acetate (497 mg, 2.69 mmol), followed by K2CO3 (619 mg, 4.48 mmol). The reaction was heated at 60° C. for overnight. After this time, the reaction was allowed to cool to RT and then was diluted with 250 mL of EtOAc. The resultant solution was washed with saturated aqueous NaCl (100 mL×3). The organic layer was dried over MgSO4, filtered, evaporated under reduced pressure to provide the title compound, 2-((7,8-bis(4-chlorophenyl)-3-oxo-[1,2,4]triazolo[4,3-b]pyridazin-2(3H)-yl)methyl)phenyl acetate, (1.13 gm) as a yellow solid.
