실험 절차

A mixture of tert-butyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (300 mg, 0.71 mmol, 1 equiv), 1-(3-chloropropyl)-3,3-dimethylindolin-2-one (200.8 mg, 0.71 mmol, 1 equiv), sodium iodide (42.7 mg, 0.285 mmol, 0.4 equiv), and potassium carbonate (295.2 mg, 2.136 mmol, 3 equiv) in 2-butanone was stirred at 81° C. for 16 h. After cooling the reaction mixture, the crude mixture was partitioned between ethyl acetate and water. The organic layer was dried over MgSO4, filtered, concentrated, and the crude residue was purified using preparatory thin layer chromatography in 5% methanol in dichloromethane to afford the title compound as cream crystals (210 mg, 47.4%); 1H NMR (400 MHz, DMSO-d6): δ 1.27 (s, 6H); 1.52 (s, 9H); 1.63 (d, 2H, J=12.4 Hz); 1.79 (bs, 2H); 2.36 (bs, 2H); 2.52-2.59 (m, 2H); 2.66-2.73 (m, 4H); 3.75 (t, 2H, J=6.8 Hz); 4.59 (s, 2H); 4.61 (s, 2H); 6.77 (t, 1H, J=6.8 and 7.2 Hz); 6.85 (d, 2H, J=8.4 Hz); 7.03 (t, 1H, J=7.6 and 6.8 Hz); 7.13 (d, 1H, J=7.6 Hz); 7.23 (t, 3H, J=8 and 7.6 Hz); 7.35 (d, 1H, J=7.2 Hz); 7.48-7.55 (m, 2H); 7.79 (s, 1H); 7.82-7.84 (m, 1H); MS for C38H46N4O4 m/z 623.18 (M+H)+.
