To a solution of (2S)-1-(4-(3-iodo-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (9) (0.65 g, 1.7 mmol) in toluene (21 mL) and EtOH (7 mL) were added 3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine 21 (0.7 g, 2.37 mmol in theory) and 2 N aq. Na2CO3 (2.5 mL). The resulting mixture was degassed under N2 for 2 minutes. Then Pd(PPh3)4 (0.19 g, 0.17 mmol) was added and the mixture was degassed again. The reaction was heated to 80-90° C. and stirred overnight. The mixture was cooled. The organic layer was separated and concentrated. The residue was purified by prep. HPLC to afford (2S)-1-(4-(1-isopropyl-3-(3-methyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-5) (0.150 mg, 16.2%) as a white solid.
