Versuchsvorschrift

A mixture of 1-(5-chloro-2-methylphenyl)piperazine (20 mg, 0.095 mmol) and 8-(2-chloroethyl)-8-azaspiro[4.5]decane-7,9-dione(20 mg, 0.087 mmol) was heated with stirring at 160° C. for 5 hours. The residue was purified by preparative HPLC (see Example 8 for conditions), giving (after removal of the solvent) the title compound as a pale yellow oil (17.3 mg, 0.043 mmol, 49%): ESI-MS m/z 404 (MH+).
