Procedure

Iodotrifluoromethane (2.0 g, 10 mmol) was bubbled through a solution of 7-bromo-3-(2-fluorophenyl)-6-(2-methyl-2H-1,2,4-triazol-3-ylmethoxy)-1,2,4-triazolo[4,3-b]pyridazine (0.10 g, 0.25 mmol) in dry DMF (2 ml) at room temperature until the required quantity of gas had dissolved. Copper powder (0.16 g, 2.5 mmol) was added and the mixture was stirred in a sealed tube at 80° C. for 18 h. The mixture was cooled, diluted with dichloromethane (50 ml) and filtered. The filtrate was washed with water (50 ml), then dried (Na2SO4), filtered and concentrated. Preparative thin layer chromatography, eluting with 3% methanol-dichloromethane, gave 3-(2-fluorophenyl)-6-(2-methyl-2H-1,2,4-triazol-3 ylmethoxy)-7-trifluoromethyl-1,2,4-triazolo[4,3-b]pyridazine (0.0061 g, 6%) as a pale yellow solid; m.p. 123-126° C.; 1H NMR (360 MHz, CDCl3) δ3.92 (3H, s), 5.60 (2H, s), 7.31 (1H, dd, J=8 and 8 Hz), 7.40 (1H, dd, J=8 and 8 Hz), 7.56-7.64 (1H, m), 7.86-7.94 (2H, m), 8.50 (1H, s); MS (ES+) m/e 393 [mH]+.
