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, 1.68 mmol) in toluene (20 mL) and EtOH (7 mL) were added N-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine 12 (1.44 g, 3.36 mmol in theory) and 2 N Na2CO3 aq. (2.5 mL). The resulting mixture was degassed under N2 for 2 minutes. Then Pd(PPh3)4 (0.2 g, 0.168 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-(6-(methylamino)pyridin-3-yl)-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ol (B-2) (0.020 g, 3.2%) as a light yellow solid.
