Versuchsvorschrift

30.0 g of 4-(4-benzoylbutyl)-1-(ethoxycarbonylamino)piperazine was dissolved in 250 ml of ethanol, and a solution of 50.5 g of potassium hydroxide in 50 ml of water was added. The mixture was heated under reflux for 3 hours. Ethanol was evaporated, and water was added. Extraction with chloroform gave 27.0 g of the title compound. The hydrochloride of this product had a melting point of 213° to 215° C. (decomp.).
