Versuchsvorschrift

Bis(pyridine)iodonium tetrafluoroborate (379 mg, 1.02 mmol) was added to a solution of 4-(pyrimidin-2-ylmethyl)phenol (200 mg, 1.07 mmol) in 9:1 DCM:TFA (6 mL) at 0° C. The mixture was stirred for 1 h, partitioned between EtOAc and water, the layers were separated, and the organic layer was washed with satd. sodium thiosulfate. The organic layer was dried over MgSO4, concentrated in vacuo, and purified by column chromatography to give 2-iodo-4-(pyrimidin-2-ylmethyl)phenol. MS (ESI) m/z: Calculated: 312.0; Observed: 313.0 (M++1).
