Versuchsvorschrift

Sodium hydride (0.0699 g, 2.91 mol) was added portionwise at 0° C. to benzyl 1-cyclohexyl-4-oxo-1,3,8-triazaspiro[4.5]decane-8-carboxylate (1.03 g, 2.77 mmol) in N,N-dimethylformamide (5 mL) and stirred at 0° C. for 10 minutes. tert-Butyl 3-(bromomethyl)benzoate (0.75 g, 2.77 mmol) was added dropwise at 0° C., the mixture allowed to warm to room temperature, and stirred overnight. The reaction was diluted with water and extracted with ethyl acetate. The extracts were washed with water and brine, dried (MgSO4) and evaporated. The residue was purified by PTLC (50% ethyl acetate/hexanes) to give product as an oil (1.37 g, 88%); 1H NMR (DMSO-d6); δ0.97 (m, 1H); 1.20 (m, 4H); 1.53 (s, 9H); 1.53-1.69 (m, 9H); 2.60 (m, 1H); 3.59 (m, 2H); 3.73 (m, 2H); 4.47 (s, 2H); 5.09 (s, 2H); 7.30-7.39 (m, 5H); 7.45-7.50 (m, 2H); 7.73 (m, 1H); 7.81 (m, 1H); MS for C33H43N3O5 m/z 562 (M+H)+.
