Versuchsvorschrift

A mixture of (S)-methyl 2-(4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)-2-phenylacetate (159 mg, 0.383 mmol, 1 equiv), 1-(3-iodopropyl)-1,3-dihydro-2H-benzimidazol-2-one (115.6 mg, 0.38 mmol, 1 equiv) and potassium carbonate (158.6 mg, 1.148 mmol, 3 equiv) in N,N-dimethylformamide was heated at 65° C. for 16 h. The reaction was cooled to ambient temperature and worked up using 5% methanol in dichloromethane and water. The organic layer was dried over MgSO4, and concentrated in vacuo. The crude mixture was purified using preparatory thin layer chromatography in 7% methanol in dichloromethane. The purified extract was lyophilized to afford the title compound as a white solid (25 mg, <10%); 1H NMR (400 MHz, DMSO-d6): δ 1.61 (bs, 2H), 1.84 (bs, 2H), 2.46 (bs, 4H); 2.50-2.51 (m, 4H); 3.74 (s, 3H); 3.85 (t, 2H, J=7.2 and 6.4 Hz); 4.15 (d, 1H, J=4.8 Hz); 4.80 (d, 1H, J=4.8 Hz); 5.89 (s, 1H)); 6.79-6.85 (m, 3H); 6.97 (d, 3H, J=2.8 Hz); 7.16-7.18 (m, 1H); 7.23 (t, 2H, J=7.2 and 8.8 Hz); 7.39-7.46 (m, 5H); 10.82 (s, 1H); MS for C32H35N5O4 m/z 554.11 (M+H)+.
