To a solution of tert-butyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.2 g, 0.47 mmol), potassium carbonate (0.097 g, 0.7 mmol) and sodium iodide (0.021 g, 0.14 mmol) in 2-butanone (5 mL), was added 3-(3-chloropropyl)-1H-indazole (0.092 g, 0.47 mmol). After stirring at 78° C. for 18 hours, the reaction mixture was filtered, concentrated and isolated by preparatory TLC (10% methanol/dichloromethane) to obtain the title compound (0.06 g, 22%); 1H NMR (DMSO-d6): δ 1.52 (s, 9H), 1.64 (d, 2H, J=14 Hz), 1.95 (t, 2H, J=6.4 Hz), 2.59-2.85 (m, 8H), 2.96 (t, 2H, J=7.6 Hz), 4.60 (d, 4H, J=9.6 Hz), 6.76 (t, 1H, J=7.2 Hz), 6.85 (d, 2H, J=8 Hz), 7.06 (t, 1H, J=6.8 Hz), 7.21 (t, 2H, J=7.6 Hz), 7.31 (t, 1H, J=7.2 Hz), 7.44-7.53 (m, 3H), 7.74-7.84 (m, 3H), 12.63 (s, 1H); MS for C35H41N5O3 m/z 580.13 (M+H)+.
