Reaction Conditions

Reaction Steps

Manganese dioxide (3.17 g, 36.5 mmol) was added to a solution of (4,6-dimethyl-pyridin-2-yl)-methanol (1.0 g, 7.30 mmol) in chloroform (30 mL) and heated at reflux overnight. The reaction mixture was cooled to 0° C. and filtered over celite, washing with further chloroform. The filtrate was evaporated to give a residue which was purified by column chromatography over silica gel (60-120 mesh) using 10% ethyl acetate in hexane as eluent to afford 4,6-dimethyl-pyridine-2-carbaldehyde (0.5 g, 51%) as a light brown liquid.
