Reaction Steps

To a solution of 7,8-bis(4-chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3(2H)-one (0.4 g, 1.1 mmol), prepared as described in Example 1 in DMF (5 mL) was added K2CO3 (0.46 g, 3.3 mmol) and 4-chlorobenzyl bromide (0.28 g, 1.3 mmol). The reaction mixture was heated at 60° C. for 20 min. After this time, water (50 mL) was added to the reaction mixture and the resultant solid was collected by filtration. The final product (0.32 g, 60%) was obtained by purification using reverse phase preparative HPLC. MS (M+H)=481; 1H NMR (CDCl3): δ 8.18 (1H, s), 7.25-7.40 (10H, m), 7.08 (2H, d, J=10.0 Hz), 5.18 (2H, s).
