Versuchsvorschrift

A mixture of (S)-3-amino-but-2-enoic acid [1-(4-methoxy-phenyl)-ethyl]-amide (10 g), 3-bromo-5-ethoxy-4-hydroxy-benzaldehyde (10.4 g) and 5-propylcyclohexane-1,3-dione (6.5 g) in ethanol (150 ml) was stirred at 80° C. for 18 hr. The mixture was concentrated in vacuo. The residue was dissolved in toluene (100 ml) and dichloromethane (50 ml) and evaporated until a precipitated formed. The solid obtained was then crystallized in EtOAc.
