(2-Ethyl-6-methyl-pyridin-4-yl)-methanol → 2-Ethyl-6-methylisonicotinaldehyde

Participants

Reaction Steps

A solution of crude (2-ethyl-6-methyl-pyridin-4-yl)-methanol (453.6 mg, 3 mmol) in DCM (30 mL) and MnO2 (2.6 g, 30 mmol) is added. The mixture is stirred at rt for 15 h, filtered and evaporated (130 mbar, 45° C.) to give crude 2-ethyl-6-methyl-pyridine-4-carbaldehyde (0.48 g); 1H NMR (CDCl3): δ 10.02 (s, 1H), 7.37 (s, 2H), 2.89 (q, J=7.6 Hz, 2H), 2.64 (s, 3H), 1.33 (t, J=7.6 Hz, 3H).
