2,6-DIMETHYLPYRIDINE-4-CARBOXALDEHYDE Usage And Synthesis

Synthesis

The general procedure for the synthesis of 2,6-dimethylpyridine-4-carbaldehyde from 2,6-dimethyl-4-hydroxymethylpyridine was as follows: 2,6-dimethyl-4-hydroxymethylpyridine (1.00 g, 7.30 mmol) was dissolved in acetonitrile (20 mL), and 1,2-benzoyl-3(1H)-keto-1-hydroxyl-1-oxo (IBX) (2.00 g, 7.30 mmol). The reaction mixture was heated to reflux for 6 hours. After completion of the reaction, the solid was removed by filtration and washed with acetonitrile. The filtrate was concentrated under reduced pressure to give 2,6-dimethylpyridine-4-carbaldehyde as a brown liquid. Yield: 0.81 g (82%).
