실험 절차

A mixture of methyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (400 mg, 0.962 mmol, 1 equiv), 1-(3-iodopropyl)-3-methyl-1H-benzo[d]imidazol-2(3H)-one (304.8 mg, 0.962 mmol, 1 equiv), and potassium carbonate (399 mg, 2.88 mmol, 3 equiv) was heated at 65° C. for 16 h. The reaction was cooled to ambient temperature and worked up using ethyl acetate and water. The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The crude residue was purified using preparatory thin layer chromatography in 5% methanol in dichloromethane to afford the title compound as an oil (427 mg, 78%); 1H NMR (400 MHz, DMSO-d6): δ 1.61 (d, 2H, J=13.2 Hz), 1.85 (t, 2H, J=7.2 and 6.8 Hz); 2.34 (d, 2H, J=6.4 Hz); 2.64-2.66 (m, 2H); 2.89 (s, 3H); 3.843 (s, 3H); 3.91 (t, 2H, J=6.4 and 6.8 Hz); 4.58 (s, 2H); 4.62 (s, 2H); 6.78 (t, 1H, J=7.2 Hz); 6.86 (d, 2H, J=8.8 Hz); 7.01-7.07 (m, 2H); 7.13-7.14 (m, 1H); 7.21-7.26 (m, 3H); 7.52-7.58 (m, 2H); 7.88 (s, 1H); 7.90 (s, 1H); MS for C33H37N5O4 m/z 568.13 (M+H)+.
