Versuchsvorschrift

To a solution of 2-(3-butyloxyphenyl)ethylamine (1.0 g) in acetonitrile (40 cm3) was added powdered potassium carbonate (0.80 g). Cinnamoyl chloride (1.03 g) was then added portionwise over a period of fifteen minutes and the reaction mixture was then stirred at room temperature for 6.5 hours after which distilled water (40 cm3) was added. The mixture was left to stand overnight and was then filtered and extracted several times with ethyl acetate. The combined ethyl acetate extracts were washed successively with potassium bicarbonate solution, water and 0.5M hydrochloric acid before drying over sodium sulphate and then evaporating down to give the product as a tan coloured oil (1.60 g).
