Versuchsvorschrift

To a solution of triethylamine (2.22 g) and 4-ethyl-6-methyl-2,4-heptadiene-1-ylamine (3.07 g) in dichloromethane (50 ml) at 0° C. was added dropwise acetic anhydride (4.08 g). After one hour, the reaction mixture was washed with water and brine, dried over anhydrous magnesium sulfate, and evaporated in vacuo. The residue was chromatographed on silica gel (10% methanol-chloroform) to give 1-acetylamino-4-ethyl-6-methyl-2,4-heptadiene (3.86 g) as an oil.
