Procedure

(rac)-8-(3,5-Bis-trifluoromethyl-benzoyl)-2-methyl-1-phenyl-1,3,8-triaza-spiro[4.5]decan-4-one (200 mg, 0.41 mmol) was dissolved in dimethyl formamide (10 mL) and sodium hydride (40 mg, 60% in mineral oil, 1 mmol) and 3-chloromethyl pyridinium chloride (82 mg, 0.5 mmol) were added and stirred at room temperature overnight. Water (30 mL) was added and the reaction mixture extacted with ethyl actetate. The organic phases were pooled, dried with MgSO4 and the solvent was evaporated. The residue was purified by chromatography on silica gel (ethyl acetate) to yield the desired product (219 mg, 93%), MS: m/e=577.0 (M+H+).
