58 mg (0.200 mmol) of 5-bromo-3-(1H-imidazo[4,5-b]pyridin-2-yl)pyridin-2-ylamine and 45.8 mg (0.220 mmol) of 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole are suspended in 2 ml of N,N-dimethylformamide in a nitrogen-filled microwave vessel, and 0.57 ml (1.142 mmol) of 2M sodium carbonate solution and 23.1 mg (0.020 mmol) of tetrakis(triphenylphosphine)palladium(0) are added. The reaction solution is irradiated with microwaves for 30 min at 120° C. in the Biotage SmithSynthesizer. The reaction mixture is evaporated to dryness, and the residue is purified by means of RP-HPLC, giving 3-(1H-imidazo[4,5-b]pyridin-2-yl)-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-ylamine; HPLC-MS [M+H]+ 292.2;
