Reaction Steps

0.125 g (0.29 mmol) of N-[2-aminopyrid-4-yl]-5-trifluoromethyl-1-[(3-fluorophenyl)-methyl]-1H-pyrrolo[2,3-b]pyridine-2-carboxamide, prepared according to the protocol described in step 15.2, 0.088 g (0.58 mmol) of 1-bromobutan-2-one and 4 mL of acetonitrile are placed in a 10 mL pressure tube specific for microwave reactors. The tube is then sealed and heated in the microwave reactor at 150° C. for two 1-hour cycles. After this time, the reaction mixture is 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. 0.076 g of the expected product is thus obtained in the form of a yellow solid.
