Versuchsvorschrift
The reaction of 2,3-dimethylpyrazine and freshly distilled propionaldehyde is carried out as described in Example I on the same molar scale. Preparative thick layer chromatography (2000μ silica gel GF, developed in 5% acetone/hexane) of the crude reaction product gives a 25% yield of 1-(2,3-dimethyl-5-pyrazinyl)-1-propanone.
