Vorschrift

To a solution of (1R,3S,5R)-3-(((tert-butyldiphenylsilyl)oxy)methyl)-6,6-dimethyl-bicyclo[3.1.1]heptan-2-amine, 77e, (0.20 g, 0.46 mmol) and 5-chloro-3-(5-fluoro-4-(methylsulfinyl)pyrimidin-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (0.14 g, 0.30 mmol) in DMF (1.5 mL) was added diisopropylethylamine (0.11 mL, 0.61 mmol). The reaction was heated to 75° C. for 18 hours. The mixture was diluted into aqueous saturated NH4Cl solution and extracted twice with EtOAc. The combined organic phases were washed twice with brine, dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified via silica gel chromatography (0-5% MeOH/CH2Cl2 gradient) to afford 78 mg of the desired product.
