Versuchsvorschrift

4-[1-(4′-Trifluoromethyl-biphenyl-4-ylmethyl)-propoxy]-benzoic acid (0.018 g, 0.04 mmol), PyBOP (0.027 g, 0.05 mmol), 3-amino-propionic acid methyl ester hydrochloride (0.011 g, 0.08 mmol), and ethyl-diisopropyl-amine (0.03 mL, 0.18 mmol) are dissolved in N,N-dimethyl-formamide (1 mL) and stirred for sixteen hours. The mixture is diluted with ethyl acetate, washed with water two times then brine. Organic layers are dried over sodium sulfate, filtered and concentrated under reduced pressure. Column chromatography on silica gel with 0-70% ethyl acetate/hexane gradient affords 0.012 g (0.02 mmol, 60%) of title compound.
