Versuchsvorschrift

A mixture of 4-(5-methyl-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (120 mg, 0.257 mmol), (R)-(+2-amino-3-methyl-1-butanol (57 l, 0.515 mmol) and diisopropylethylamine (90 l, 0.515 mmol) in THF (4 mL) was heated at reflux for 1 hour. The reaction mixture was concentrated in vacuo and the residue was purified on silica gel by flash column chromatography to give the title compound as a colourless glassy solid (97 mg, 77% yield).
