Procedure

A mixture of tert-butyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (500 mg, 1.186 mmol, 1 equiv) and methyl 3-(1-(3-chloropropyl)-1H-indol-3-yl)propanoate (384.4 mg, 1.186 mmol, 1 equiv), sodium iodide (88.88 mg, 0.593 mmol, 0.5 equiv) and potassium carbonate (492 mg, 3.56 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 preparative thin layer chromatography in 5% methanol in dichloromethane to afford the title compound as a white solid (442 mg, 56%); 1H NMR (400 MHz, DMSO-d6): δ 1.52 (s, 9H); 1.63 (d, 2H, J=12 Hz); 1.90-1.96 (m, 2H); 2.24 (bs, 2H); 2.61-2.70 (m, 8H); 2.96 (t, 2H, J=7.6 Hz); 3.57 (s, 3H); 4.20 (t, 2H, J=6.4 and 6.8 Hz); 4.59 (s, 2H); 4.61 (s, 2H); 6.77 (t, 1H, J=7.2 and 7.6 Hz); 6.87 (d, 2H, J=8.4 Hz); 6.99 (t, 1H, J=7.6 Hz); 7.10 (t, 1H, J=7.6 and 6.8 Hz); 7.17 (s, 1H); 7.24 (t, 2H, J=7.2 and 8.4 Hz); 7.46-7.53 (m, 4H); 7.79-7.84 (m, 2H); MS for C40H48N4O5 m/z 665 (M+H)+.
