Reaction Steps

A mixture of (S)-tert-butyl 2-(4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)-2-phenylacetate (300 mg, 0.71 mmol, 1 equiv), 4-chloro-1-phenylbutan-1-one (130 mg, 0.71 mmol, 1 equiv), sodium iodide (42.6 mg, 0.28 mmol, 0.4 equiv), and potassium carbonate (196.3 mg, 1.42 mmol, 2 equiv) in 2-butanone was stirred at 81° C. for 16 h. After cooling the reaction mixture, the crude mixture was partitioned between ethyl acetate and water. The organic layer was dried over MgSO4, filtered, concentrated, and the crude residue was purified using the Biotage flash chromatography system (SNAP 10 g cartridge, Rf=0.5, gradient—1%-10% methanol in dichloromethane) to afford the title compound as an oil (200 mg, 50%); MS for C35H41N3O4 m/z 568.4 (M+H)+.
