Procedure
To a solution of 6-(2-chlorophenyl)-7-(4-chlorophenyl)-N-(4-(trifluoromethyl)benzyl)-[1,2,4]triazolo[4,3-b]pyridazine-3-carboxamide (Example 34) (22 mg, 0.041 mmol) in anhydrous DMF at room temperature was added sodium hydride (6.5 mg, 0.164 mmol). The resulting suspension was stirred at room temperature for 5 min, then iodomethane (25 μL, 0.4 mmol) was added. The reaction mixture was stirred at room temperature for 1 h. The mixture was diluted with EtOAc (30 mL), washed with water, saturated aqueous NaCl, dried (Na2SO4) and concentrated under reduced pressure. The crude product was purified using a silica gel cartridge (4 g) eluting with a gradient of EtOAc (0-60%) in hexanes to afford 15 mg (66%) of the title compound as a white powder. HPLC/MS (method A): retention time=3.85 min, (M+H)+=556.3
