Participants

Reaction Steps

tert-Butyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.25 g, 0.593 mmol), 3-(2-oxoindolin-3-yl)propyl methanesulfonate (0.16 g, 0.593 mmolmmol), sodium iodide (0.027 g, 0.178 mmol) and potassium carbonate (0.12 g, 0.890 mmol) in 2-butanone (8 mL) were stirred at 78° 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 (0.29 g, 82%); MS for C36H42N4O4 m/z 595 (M+H)+.
