Reaktionsschritte
The reaction of trimethylpyrazine 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 48% yield of 1-(2,3,5-trimethyl-6-pyrazinyl)-1-propanone (mp 65°-67° C.).
