Vorschrift

A solution of 5-chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 23a, (0.50 g, 1.08 mmol) in THF (4 mL) was treated with (1S,2S)-cyclohexane-1,2-diamine (0.27 g, 2.37 mmol) and iPr2NEt (2.15 mmol) at 120° C. for 10 minutes. The mixture was concentrated in vacuo. The resulting residue was purified by silica gel chromatography (0-20% MeOH—CH2Cl2) to provide the desired intermediate as a white solid (410 mg).
