Versuchsvorschrift
2,3-Dihydropyran (25.0 mL, 270 mmol) was added to (2R)-2-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)propan-1-ol (11.00 g, 51.97 mmol) (see Preparation 3) and pyridinium toluene-4-sulphonate (3.92 g, 15.6 mmol) in DCM (150 mL). The reaction mixture was washed with water (200 mL) and the aqueous phase was extracted with DCM (2×150 mL). The combined organic phases were dried over magnesium sulfate and evaporated in vacuo. The crude material was purified by column chromatography on silica gel (gradient of heptane:EtOAc 100:0 to 70:30) to afford the title compound as a yellow oil in 100% yield, 15.65 g.
