Versuchsvorschrift

2-Fluoro-4-imidazol-1-ylmethyl-benzonitrile (as described in Step E above) (0.080 g, 0.4 mmol), 2-(2-oxo-piperidin-1-yl)-phenol (as described in Step F above) (0.091 g, 0.5 mmol) and cesium carbonate (0.261 g, 0.8 mmol) were combined in DMF (2.0 mL) and heated at 50° C. for 18 hr. The reaction mixture was partitioned between EtOAc and a minimum volume of H2O. Additional product was salted out from the aqueous layer with solid NaCl, and extracted into EtOAc. The organic layers were combined, dried (Na2SO4), filtered and concentrated to give the title compound after RP HPLC on a Waters Prep Pak column eluting with a 0.1% TFA/H2O: 0.1% TFA/CH3CN gradient followed by conversion to the free base.
