Participants

Reaction Steps

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 (3×) 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. Exact mass (Cl): calculated for C34H39Cl2N4O4 (M+H): 637.2348. Found 637.2322.
