Procedure

A mixture of (R)-tert-butyl 3-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)piperidine-1-carboxylate (1.7 g, 5.05 mmol) and NIS (1.25 g, 5.55 mmol) in DMF (20 mL) was stirred for 12 h at room temperature. Water was added to the mixture, which was extracted with EA, the combined organic layers were dried and purified by column to give (R)-tert-butyl 3-(4-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)piperidine-1-carboxylate (2.0 g, 86% in yield).
