A mixture of 9.8 g (0.05 mol) of 1,3-dioxo-6-cyclohexyl-cyclohexane, 12.9 g (0.15 mol) of anhydrous piperazine and 150 ml of toluene is reacted and worked up as described in Example 1. For purification, column chromatography is included (corresponding to Example 2). (3-Oxo-6-cyclohexyl-1-cyclohexen-1-yl)-piperazine is obtained as an oil in an amount of 9.9 g (=76% yield) with an RF value of 0.36 (conditions corresponding to Example 1). The dihydrochloride has a melting point of 258°-261° C. (decomposition).
