Procedure

A solution of methyl 3-((8-(3-(3-methyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl)propyl)-4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (326 mg, 0.575 mmol, 1 equiv) and lithium hydroxide (48.3 mg, 1.15 mmol, 2.0 equiv) in a 4:1 mixture of methanol and water (5 ml t/v) was stirred at 35° C. for 24 hrs. The reaction was concentrated in vacuo and purified using preparatory high performance liquid chromatography. The combined pure fractions were lyophilized to afford the acetate salt of the title compound as a white solid (56 mg, 17%); 1H NMR (400 MHz, DMSO-d6): δ 1.61 (d, 2H, J=13.6 Hz), 1.84 (t, 2H, J=6.8 Hz); 2.37 (t, 2H, J=7.2 Hz, J=6.4 Hz); 2.54-2.59 (m, 2H); 2.66-2.73 (m, 4H); 3.32 (s, 3H); 3.91 (t, 2H, J=6.8 Hz); 4.58 (s, 2H); 4.60 (s, 2H); 6.76 (t, 1H, J=7.2 Hz); 6.85 (d, 2H, J=8 Hz); 7-7.07 (m, 2H); 7.12-7.15 (m, 1H); 7.2-7.26 (m, 3H); 7.47-7.53 (m, 2H); 7.86-7.88 (m, 2H); 12.9 (bs, 1H); MS for C32H35N5O4 m/z 554.05 (M+H)+.
