The mixture was quenched by the careful addition of water, the layers were separated, and the organic layer was washed with water three times. The combined organic extracts were dried over MgSO4, concentrated in vacuo, and purified by column chromatography to give 2-iodo-4-(pyridin-3-ylmethyl)phenol as a yellow oil. MS (ESI) m/z: Calculated: 311.0; Observed: 312.3 (M++1).
