Versuchsvorschrift

N-hexylbenzylamine (0.6 g, 3.136 mmol) and 3-(4-hydroxyphenyl)propionic acid (0.52 g 3.136 mmol) were mixed in DMF (10 ml) and the mixture was cooled. HOBT (0.424 g, 3.136 mmol) and the TBTU (1 g, 3.136 mmol) reagent were added followed by DIPEA (1.216 g, 9.409 mmol). The mixture was stirred at room temperature overnight and then evaporated. The resulting mixture was partitioned between ethyl acetate and sodium hydrogencarbonate aqueous solution (sat.). The aqueous portion was extracted with ethyl acetate and the combined organic extracts dried with magnesium sulphate and then evaporated. Chromatography of the residue on a column (ISOLUTE® SI, 5 g/25 ml) using ethyl acetate/heptane (10:90, then 25:75) as eluant gave 760 mg the desired product, yield 71%.
