Procedure

To a suspension of 2-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (B-7-7) (1.8 g, 2.3 mmol in the theory) and (2S)-1-(4-(3-iodo-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-1-3) (0.45 g, 1.2 mmol) in toluene/EtOH (3:1, 50 mL) was added aq. Na2CO3 (1.7 mL, 2 M). The mixture was degassed under N2 for 2 minutes, Pd(PPh3)4 (0.05 g, 0.042 mmol) was added into the mixture and degassed again. The mixture was stirred at 80° C. for 30 hours. TLC (CH2Cl2: MeOH=20:1) showed that the reaction was complete. Water (50 mL) and EtOAc (50 mL×3) were added into the mixture. The organic layer was separated, dried over anhydrous Na2SO4 and concentrated to give crude product which was purified via prep. HPLC to afford (2S)-1-(4-(1-isopropyl-3-(2-methyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-7) (0.169 g, 18.6%) as a white solid.
