Versuchsvorschrift

To a solution of {4-[(2S)-2,3-diethoxy-3-oxopropyl]phenoxy}acetic acid (0.108 g, 0.36 mmol) in methylene chloride (3.6 mL) were added N-(cyclohexylmethyl)-N-heptylamine hydrochloride (0.090 g, 0.36 mmol) and DMAP (0.098 g, 0.80 mmol) followed by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.070 g, 0.36 mmol) and the reaction mixture was stirred at room temperature overnight. The mixture was diluted with methylene chloride (25 mL) and the organic phase was washed with 5% HCl (3×25 mL), aqueous NaHCO3 (25 mL) and brine (25 mL), dried over Na2SO4 and concentrated in vacuo. Purification on a prepacked column of silica gel (Isolute® SPE Column, 5 g Si/25 mL) with methanol (0-1% gradient) in methylene chloride as the eluent yielded 0.103 g (58%) of a colourless oil.
