Versuchsvorschrift

Under ice-cooling, 9.96 g (52 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride was added to a solution of 8.8 g (52 mmol) of 4-(chloromethyl)benzoic acid, 10 g (52 mmol) of 1-aminocyclohexanecarboxylic acid methyl ester hydrochloride, 15 g (152 mmol) of triethylamine and 8.63 g (56 mmol) of 1-hydroxybenzotriazole in methylene chloride. After the mixture was stirred at room temperature overnight, the reaction solvent was distilled off under reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate twice. The obtained organic layer was washed with a 10% aqueous potassium hydrogensulfate solution, a saturated aqueous sodium hydrogencarbonate solution and then saturated brine, and it was dried with anhydrous sodium sulfate. The obtained residue was purified by silica gel column chromatography to obtain 8.5 g (53%) of the title compound.
