Procedure
To round bottom flask was added 6-chloro-7,8-bis(4-chlorophenyl)-[1,2,4]triazolo[4,3-b]pyridazine (37.6 mg, 0.10 mmol), 4-methyoxybenzyl alcohol (0.15 mmol), THF (1 ml) and 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazaphosphorine (BEMP) (30 mg, 0.11 mmol). The reaction was heated to 50° C. and stirred at this temperature for 40 hrs. The solvent was removed and the residue was purified using preparative HPLC to give pure product 7,8-bis(4-chlorophenyl)-6-(4-methoxybenzyloxy)-[1,2,4]triazolo[4,3-b]pyridazine as a solid. HPLC retention time (method C) 7.91 min; LCMS (M+H)=477.10.
