Procedure

2-[1-(2,6-Dimethoxy-benzoyl)-3-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-ethyl methanesulfonate (200 mg, 0.398 mmol), and 1-phenyl-1,3,8-triaza-spiro[4.5]decan-4-one (100 mg, 0.432 mmol) were dissolved in THF/H2O (4 mL/1 mL) and treated with potassium carbonate (110 mg, 0.796 mmol, 2 eq.) at reflux for 22 hours. The solution was concentrated in vacuo and the aqueous phase was extracted (3x) with dichloromethane. The organic phase was dried over magnesium sulfate, filtered, and concentrated in vacuo. The residue was chromatographed on silica gel (40 g) with a gradient from ethyl acetate to 10% methanol in dichloromethane to give 130 mg (51%) of the title compound.
