Versuchsvorschrift

4-((R)-1-aminoethyl)cyclohexanol (309.4 mg, 2.16 mmol) was dissolved in THF (10 mL) and DMF (4 mL) and stirred over molecular sieves for 10 minutes. Diisopropylethylamine (376.3 μL, 2.160 mmol) was added, followed by 2-chloro-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (516.1 mg, 1.080 mmol). The reaction mixture was stirred under nitrogen at ambient temperature for 18 hours. The molecular sieves was removed by filtration and washed with EtOAc. The filtrate was washed with water, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography (ISCO Companion|, 80 g column, 0-100% EtOAc/DCM) to afford the title compound as a yelow solid (558 mg, 88% yield).
