1,3-Diiodo-5,5-dimethylimidazolidine-2,4-dione → tert-butyl N-[2-[2-chloro-6-(diethoxymethyl)-5-iodo-pyrrolo[2,3-d]pyrimidin-7-yl]ethyl]carbamate

Participants

Reaction Steps

To 0.1 g (0.00025 mole) of tert-butyl N-[2-[2-chloro-6-(diethoxymethyl)pyrrolo[2,3-d]pyrimidin-7-yl]ethyl]carbamate in acetonitrile (2 mL) was added 1,3-Diiodo-5,5-dimethylhydantoin (95 mg, 1 eq), and solid NaHCO3 (63 mg, 3 eq). Stir at room temperature for 16 hrs. Filter, concentrate and then column with hexane/ethylacetate (0-50%) to afford tert-butyl N-[2-[2-chloro-6-(diethoxymethyl)-5-iodo-pyrrolo[2,3-d]pyrimidin-7-yl]ethyl]carbamate as a pale yellow solid 0.03 g. LCMS (ESI) 525 (M+H).
