Procedure

Dichlorobis(triphenylphosphine)palladium(II) (0.073 g, 0.10 mmol) was added in one portion to (3R)-4-(2-chloro-6-(1-(S-methylsulfonimidoyl)cyclopropyl)pyrimidin-4-yl)-3-methylmorpholine (1.383 g, 4.18 mmol), 2M aqueous sodium carbonate solution (2.508 ml, 5.02 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (1.665 g, 4.18 mmol) in DME:water 4:1 (100 ml) under nitrogen. The reaction mixture was stirred at 90° C. for 6 hours. The reaction mixture was concentrated and diluted with EtOAc (400 ml), and washed sequentially with water (300 ml) and saturated brine (75 ml). The organic layer was dried over MgSO4, filtered and evaporated onto silica gel (30 g). The resulting powder was purified by flash chromatography on silica, eluting with a gradient of 0 to 5% MeOH in DCM. Pure fractions were evaporated to dryness to afford (3R)-3-methyl-4-(6-(1-(S-methylsulfonimidoyl)cyclopropyl)-2-(1-tosyl-1H-pyrrolo[2,3-b]pyridin-4-yl)pyrimidin-4-yl)morpholine (2.174 g, 92%); 1H NMR (400 MHz, CDCl3) 1.37 (3H, d), 1.56 (2H, m), 1.83 (2H, q), 2.37 (4H, s), 3.16 (3H, s), 3.36 (1H, td), 3.60 (1H, td), 3.74 (1H, dd), 3.85 (1H, d), 4.01-4.19 (2H, m), 4.49 (1H, s), 6.95 (1H, d), 7.28 (2H, d, obscured by CDCL3 peak), 7.44 (1H, t), 7.82 (1H, d), 8.02-8.11 (3H, m), 8.52 (1H, d); m/z: (ES+) MH+, 567.11.
