Versuchsvorschrift
To a stirred solution of 7-[1-(Tetrahydro-pyran-2-yloxymethyl)-cyclopropyl]-7H-pyrrolo[2,3-d]pyrimidine (Preparation 248, 390 mg, 1.43 mmol) in DMF (8 mL) was added N-iodosuccinimide (481.5 mg, 2.14 mmol) and stirred at room temperature for 4 hours. The reaction mixture was quenched with water (8 mL) and extracted with ethyl acetate (3×20 mL). The combined organic layer was washed with water (5×15 mL), brine (10 mL), dried over sodium sulphate and evaporated in vacuo. The crude material was purified by column chromatography on silica gel (gradient of dichloromethane:methanol 100:0 to 99:1) to afford the title compound as a solid in 79% yield, 450 mg.
