Procedure
1.04 g (5.22 mmol) methyl (S)-2-amino-3-cycloheptyl-propionate were stirred with 0.62 ml (5.22 mmol) benzylbromide, 1.44 g (10.4 mmol) potassium carbonate and 20 ml DMF at 100° C. for 3.5 h. Then water was added and the mixture was extracted with ethyl acetate. The organic phase was evaporated down and the residue was purified by flash chromatography.
