실험 절차

To a solution of tert-butyl 2-methyl-2-(4-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)phenoxy)propanoate (0.22 g, 0.46 mmol) and potassium carbonate (0.095 g, 0.69 mmol) in N,N-dimethylformamide (4 mL), was added 1-(3-iodopropyl)-1,3-dihydro-2H-benzimidazol-2-one (0.139 g, 0.46 mmol). After stirring at 55° C. for 16 hours, the reaction mixture was diluted with ethyl acetate (100 mL), washed with water and brine. The organic phase was dried over MgSO4, filtered, concentrated and isolated by preparatory TLC (10% methanol/dichloromethane) to obtain the title compound (0.26 g, 86%); 1H NMR (DMSO-d6): δ 1.35 (s, 9H), 1.49 (s, 6H), 1.56 (d, 2H, J=13.6 Hz), 1.82 (t, 2H, J=6.4 Hz), 2.32-2.34 (m, 2H), 2.45-2.50 (m, 2H), 2.66-2.72 (m, 4H), 3.85 (t, 2H, J=6.8 Hz), 4.45 (s, 2H), 4.53 (s, 2H), 6.77-6.84 (m, 5H), 6.96 (d, 3H, J=3.2 Hz), 7.17-7.24 (m, 5H), 10.79 (s, 1H); MS for C38H47N5O5 m/z 654.18 (M+H)+.
