Versuchsvorschrift

A solution of (2S)-2-((3S)-3-{[(6-chloro-2-naphthyl)sulfonyl]amino}-2-oxopyrrolidin-1-yl)propanoic acid (0.408 g) in DCM (21 ml) was treated with 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.394 g), HOBT (0.278 g) and triethylamine (0.286 ml) and stirred at room temperature for 1 h. A solution of benzyl (3S)-piperidin-3-ylcarbamate (0.361 g) in DCM (1 ml) was then added and stirring continued for 72 h. The mixture was partitioned between DCM and water. The separated organic extracts were washed with water and brine, dried (over magnesium sulphate), and concentrated under reduced pressure. The residue was purified using Biotage™ chromatography (eluting with hexane:ethyl acetate 1:7→1:10) to give the title compound (0.268 g) as an oil.
