Reaction Steps
Compound 21 was prepared according to a process similar to that described in Example 20, by reacting 0.4 g (1.40 mmol) of 5-fluoro-1-[(3-fluorophenyl)methyl]-1H-indole-2-carboxamide, prepared according to the protocol described in step 1.2, with 0.41 g (1.54 mmol) of ethyl 6-bromoimidazo[1,2-b]pyridazine-2-carboxylate, prepared according to the protocol described in step 21.1, in the presence of 80 mg (0.42 mmol) of copper iodide, 0.38 g (2.79 mmol) of potassium carbonate and 53 mg (0.46 mmol) of trans-1,2-cyclohexanediamine in 10 mL of dioxane. 20 mg of the expected product are thus obtained.
