実験手順

To a solution of (2-methyl-2H-1,2,4-triazol-3-yl)methanol (0.11 g, 1.0 mmol) (prepared using the conditions described in EP-A-421210) in DMF (5 ml) was added sodium hydride (0.04 g of a 60% dispersion in oil, 1 mol eq) and the reaction mixture was stirred at room temperature for 30 min. After this time 6-chloro-3-(2-fluorophenyl)-7-(thien-2-yl)-1,2,4-triazolo[4,3-b]pyridazine (0.19 g, 0.57 mmol) was added and the reaction mixture was stirred at room temperature for 18 h. The reaction mixture was diluted with water (70 ml) and the precipitate was collected. The solid was purified by boiling in ethyl acetate and collecting the title compound as a yellow solid (0.01 g, 12%). 1H NMR (250 MHz, d6-DMSO) δ 3.83 (3H, s), 5.64 (2H, s), 7.24 (1H, dd, J 4 and 4 Hz), 7.44-7.55 (2H, m), 7.66-7.71 (1H, m), 7.82 (1H, d, J=5 Hz), 7.96-8.01 (3H, m), 8.23 (1H, s).
