Procedure

To a solution of methyl 3-(4-oxo-8-(3-(2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl)propyl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)-3-phenylpropanoate (0.22 g, 0.39 mmol) in methanol (3 mL) was added lithium hydroxide monohydrate (0.033 g, 0.78 mmol) in water (1 mL). After stirring at room temperature for 24 h, the reaction mixture was concentrated in vacuo and isolated by reverse phase HPLC to obtain the title compound as an acetate salt (0.080 g, 37%); 1H NMR (DMSO-d6): δ 1.45 (d, 1H, J=13.2 Hz), 1.55 (d, 1H, J=13.2 Hz), 1.81 (t, 2H, J=6.8 Hz), 2.33 (t, 2H, J=6.8 Hz), 2.48-2.50 (m, 2H), 2.57-2.68 (m, 4H), 3.07-3.10 (m, 2H), 3.84 (t, 2H, J=6.8 Hz), 4.37 (d, 1H, J=5.2 Hz), 4.70 (d, 1H, J=5.2 Hz), 5.52 (t, 1H, J=7.2 Hz), 6.75 (t, 1H, J=7.2 Hz), 6.86 (d, 2H, J=8.4 Hz), 6.96 (d, 3H, J=3.2 Hz), 7.16-7.24 (m, 3H), 7.29-7.32 (m, 1H), 7.37 (d, 4H, J=4 Hz), 10.80 (s, 1H), 11.50 (br, 1H); MS for C32H35N5O4 m/z 554.05 (M+H)+.
