Procedure

To a refluxing 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)methyl)benzoate (0.2 g, 0.36 mmol) and (S)-3-quinuclidinol (0.184 g, 1.44 mmol) in toluene (2 mL), was added titanium(IV)-i-propoxide (0.105 mL, 0.36 mmol, d=0.97). After refluxing for 18 h, the reaction mixture was diluted with 5% methanol/dichloromethane, washed with water and brine. The organic phase was dried over MgSO4, filtered, concentrated and isolated by reverse phase HPLC to obtain the title compound as an acetate salt (0.08 g, 34%); 1H NMR (DMSO-d6): δ 1.32-1.36 (m, 1H), 1.51-1.54 (m, 4H), 1.79-1.84 (m, 3H), 1.99-2.01 (m, 1H), 2.35 (t, 2H, J=6.8 Hz), 2.52-2.72 (m, 11H), 3.15-3.21 (m, 1H), 3.85 (t, 2H, J=6.8 Hz), 4.61 (d, 4H, J=13.2 Hz), 4.90-4.92 (m, 1H), 6.76 (t, 1H, J=6.8 Hz), 6.84 (d, 2H, J=8 Hz), 6.96 (d, 3H, J=2.4 Hz), 7.17-7.24 (m, 3H), 7.52-7.59 (m, 2H), 7.87-7.92 (m, 2H), 10.80 (br, 1H); MS for C38H44N6O4 m/z 649.11 (M+H)+.
