Procedure
A microwave tube was placed 5-chloro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine (2.13 g, 4.93 mmol) and (3S)-3-[(2-chloro-5-fluoro-pyrimidin-4-yl)amino]cyclohexanone in DME (22.2 mL) and aqueous Na2CO3 (5.13 mL of 2 M solution, 10.26 mmol) solution. The mixture was deoxygenated with nitrogen for 20 min. To the reaction mixture was added tetrakis triphenylphosphane palladium (0.47 g, 0.41 mmol). The reaction was sealed and heated to 120° C. for 30 min. The reaction was diluted with ethyl acetate (40 mL), filtered through Celite. The filtrate was washed with brine, dried (MgSO4), filtered and concentrated in vacuo. Purification via silica gel chromatography using 10-80% EtOAc/hexanes gradient afforded (3S)-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]cyclohexanone, 64a.
