Reaction Steps

To a solution of N-(3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)phenyl)methanesulfonamide (0.2 g, 0.48 mmol), sodium iodide (0.029 g, 0.19 mmol) and potassium carbonate (0.133 g, 0.96 mmol) in 2-butanone (5 mL), was added 1′-(3-chloropropyl)spiro[cyclopropane-1,3′-indolin]-2′-one (0.114 g, 0.48 mmol). After stirring at 78° C. for 18 hours, the reaction mixture was filtered and isolated by preparatory TLC (10% methanol/dichloromethane) to obtain the title compound (0.09 g, 31%); 1H NMR (DMSO-d6): δ 1.51 (t, 2H, J=3.6 Hz), 1.58 (t, 2H, J=3.6 Hz), 1.64 (d, 2H, J=13.2 Hz), 1.80 (br, 2H), 2.37 (br, 2H), 2.51-2.57 (m, 2H), 2.68-2.73 (m, 4H), 2.96 (s, 3H), 3.82 (t, 2H, J=6.8 Hz), 4.52 (s, 2H), 4.58 (s, 2H), 6.76 (t, 1H, J=7.6 Hz), 6.84 (d, 2H, J=8.4 Hz), 6.96-7.02 (m, 3H), 7.09 (s, 1H), 7.12 (d, 1H, J=8 Hz), 7.17-7.24 (m, 4H), 7.32 (t, 1H, J=8 Hz), 9.81 (s, 1H); MS for C34H39N5O4S m/z 614.4 (M+H)+.
