Procedure
To a solution of tert-butyl 2-((1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (0.175 g, 0.4 mmol), sodium iodide (0.018 g, 0.12 mmol) and potassium carbonate (0.083 g, 0.6 mmol) in 2-butanone (4 mL), was added 1-(3-chloropropyl)indolin-2-one (0.095 g, 0.4 mmol). After stirring at 78° C. for 18 hours, the reaction mixture was filtered and isolated by Biotage flash chromatography (1-10% methanol/dichloromethane) and preparatory TLC (10% methanol/dichloromethane) to obtain the title compound (0.077 g, 31%); 1H NMR (DMSO-d6): δ 1.56 (s, 9H), 1.67 (d, 2H, J=12.4 Hz), 2.02 (br, 2H), 2.28-2.34 (m, 2H), 2.62-2.67 (m, 2H), 3.17-3.23 (m, 2H), 3.52-3.56 (m, 4H), 3.72 (t, 2H, J=6.4 Hz), 4.61 (s, 2H), 4.82 (s, 2H), 6.11-7.14 (m, 6H), 7.23-7.27 (m, 3H), 7.41 (t, 1H, J=7.6 Hz), 7.57 (t, 1H, J=7.6 Hz), 7.82 (d, 1H, J=8 Hz); MS for C36H41FN4O4 m/z 613.15 (M+H)+.
