80 °C

A magnetically stirred mixture of (2,4-dimethyl-pyridin-3-yl)-methanol (0.342 g, 2.5 mmol) and IBX (1.40 g, 5 mmol) in acetonitrile (5 mL) placed in a round bottom flask was heated at 80° C. in an oil bath for 1 h. The mixture was cooled to room temperature and filtered. The solid was washed with acetonitrile. The filtrate was concentrated and applied to a short silica gel column and chromatographed using hexane/ethyl acetate solvent mixture (30-60% ethyl acetate). Product containing fractions were combined and the solvent was evaporated to afford 0.283 g of 2,4-dimethyl-pyridine-3-carbaldehyde as a white solid. MS: (M+H)/z=136.
