Versuchsvorschrift

4-Chloro-2-trimethylacetamido-pyrrolo[2,3-d]pyrimidine (9a, 10.9 g, 43.24 mmol) was dissolved in anhydrous THF (120 mL) under nitrogen. After the addition of N-iodosuccinimide (10.7 g, 47.56 mmol), the mixture was stirred at RT for 1 h. The solvent was then removed in vacuo. The residue dissolved in EtOAc (100 mL) and washed with 1 M sodium thiosulfate (3×100 mL). Column chromatography purification (2% MeOH in DCM, isocratic) yielded 9b (12.9 g).
