0.056 g (0.30 mmol) of copper iodide, 0.2 g (0.59 mmol) of 5-trifluoromethyl-1-[(3-fluorophenyl)methyl]-1H-indole-2-carboxamide, prepared according to the protocol described in step 17.1, 0.12 g (0.71 mmol) of 2-amino-4-bromopyridine, 0.33 g (2.38 mmol) of potassium carbonate and 4 mL of anhydrous dioxane are placed in a 10 mL pressure tube specific for microwave reactors. The suspension is degassed for a few minutes and 0.04 mL (0.3 mmol) of trans-1,2-cyclohexanediamine is then added. The tube is then sealed and heated in the microwave reactor at 170° C. for 45 minutes. After this time, the suspension cooled to room temperature is poured into 30 mL of water and then extracted with 2×40 mL of dichloromethane. The combined organic phases are dried over magnesium sulfate and concentrated under reduced pressure. The crude reaction product is then purified by chromatography on a column of silica gel, eluting with a mixture of dichloromethane and methanol. 0.186 g of the expected product is thus obtained.
