Versuchsvorschrift

A mixture of 2-[(2S)-1-[3-(N-benzyl-N-methylcarbamoyl)propanoyl]pyrrolidin-2-yl]-2-oxoacetic acid ethyl ester (626 mg), potassium carbonate (277 mg), methanol (7 ml) and water (4 ml) was stirred for 1 hr. at room temperature. Water was added to the reaction solution. The mixture was extracted with EtOAc. The extract was washed, dried and evaporated to give the title compound (458 mg) having the following physical data:
