Reaction Steps
tert-Butyl 7-{4-(4-cyanophenyl)-4-[4-(tetrahydro-2H-pyran-2-yloxy)-phenoxy]butyl}-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate (from step (iv) above; 2.33 g; 4.0 mmol), was dissolved in THF (40 mL), acetic acid (20 mL) and H2O (10 mL). The mixture was stirred at 35° C. for 2 days. The mixture was made basic with 10 M NaOH (whilst cooling). Extraction with DCM, separation of the organic layer, evaporation of the solvent and chromatography on silica (CH3CN) gave 1.43 g (72%) of the title compound.
