Vorschrift

tert-Butyl 3-((1-cyclohexyl-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.30 g, 0.585 mmol), 4-iodobutyrophenone (0.17 g, 0.585 mmol), and potassium carbonate (0.12 g, 0.878 mmol) in N,N-dimethylformamide (8 mL) were stirred at 65° C. for 2 hours. The reaction was diluted with ethyl acetate, washed with water and brine, dried (MgSO4), and evaporated. The residue was purified by PTLC (5% methanol/dichloromethane) to give product as an oil (0.28 g, 82%); MS for C35H47N3O4 m/z 574 (M+H)+.
