Reaction Steps

5-Chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 15a, (0.25 g, 0.53 mmol) and (1S,2S)-cyclohexane-1,2-diamine (0.12 g, 1.08 mmol) were dissolved in THF (3.0 mL), and heated to 140° C. for 20 minutes in a sealed vial. The solvent was evaporated in vacuo and the residue was purified by silica gel chromatography (0%-15% MeOH/CH2Cl2) to provide product, 15b, as a white foamy solid (220 mg, 79% yield).
