Participants

Reaction Steps

Analogously to Example 1, by using equivalent quantities, reacting N-(p-chlorobenzoyl-4-[(1-ethynylcyclohexyl-1)-amino]butyric acid and ethyl 4-[(3-ethyl-1-pentyn3-yl)amino]butyrate and suitable processing, dissolving the evaporation residue in ethanol, adding an ethanolic solution of potassium hydroxide, stirring for 12 hours at room temperature and further processing yields N-[p-chlorobenzoyl)-4-(1-ethynylcyclohexyl-1-amino)butyryl]-4-(3-ethyl-1-pentyn-3-ylamino)butyric acid.
