Reaction Steps
A mixture of 1-(2,5-difluorophenyl)piperazine (20 mg, 0.10 mmol) and (S)-8-(2-chloro-1-methylethyl)-8-azaspiro[4.5]decane-7,9-dione (20 mg, 0.082 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 (10.8 mg, 0.026 mmol, 32%): ESI-MS m/z 406 (MH+).
