4-Pyridinepropanol → 3-(Pyridin-4-yl)propanal

Participants

Reaction Steps

4-pyridinepropanol (0.60 mL, 4.65 mmol) was added to a solution of the Dess-Martin reagent (2.37 g, 5.58 mol) in dichloromethane (30 mL). After 60 min at RT, the solution was quenched with 10% aq. Na2S2O3, washed with sat. aq. NaHCO3 and brine, dried (Na2SO4), and concentrated. Purification by chromatography (SiO2, 4:1 hexane/ethyl acetate) yielded the title compound. MS 136 (M+H)+.
