YieldReaction ConditionsOperation in experiment
65% A solution of 31 .9 g (199 mmol) 2,3-dif luoro-4-methoxyphenol in 450 mL of dimethylsulfoxide was treated with 7.96 g (199 mmol) of sodium hydride and stirred at room temperature for 1 hour. Then 16 g (33.2 mmol) of 4-{6-bromo- 8-[(3,3,3-trifluoropropyl)amino]imidazo[1 ,2-b]pyridazin-3-yl}-N-cyclopropyl-2- methylbenzamide, which was prepared according to intermediate example 31a, was added and the mixture was heated overnight at 130C. After cooling, 300 mL ethyl acetate were added and the organic phase is washed with water. After evaporation of the organic phase, the residue was triturated with 200 mL EtOH to give 12.05 g (65%) of the title compound. 1 H-NMR (DMS0-d6): delta= 0.47-0.53 (2H), 0.62-0.70 (2H), 2.11 (3H), 2.72 (2H), 2.80 (1 H), 3.64 (2H), 3.92 (3H), 6.22 (1 H), 7.12 (1 H), 7.18 (1 H), 7.27 (1 H), 7.63 (1 H), 7.72 (1 H), 7.75-7.81 (1 H), 7.97 (1 H), 8.24 (1 H) ppm.
