Reaction Steps

To a solution of (2S)-1-(4-(3-iodo-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-1-3) (0.34 g, 0.885 mmol) in toluene (30 mL) and EtOH (10 mL) were added 2,3-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (B-6-5) (0.7 g, 1.77 mmol in theory) and 2 N aq. Na2CO3 (1.3 mL). The resulting mixture was degassed under N2 for 2 minutes. Then Pd(PPh3)4 (68 mg, 0.058 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-(3-(2,3-dimethyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-6) (0.170 mg, 23.6%) as a light yellow solid.
