Reaction Steps
To 4-chloro-1-(2,2,2-trifluoroethyl)-2-(trifluoromethyl)-1H-benzimidazol-5-yl trifluoromethanesulfonate (0.053 g, 118 mmol) in DMF (3 mL) was added zinc cyanide (0.008 g, 0.071 mmol) and palladium tetrakistriphenylphosphine (0.014 g, 0.012 mmol). The resulting mixture was heated over night under N2 atm at 140° C. The cooled reaction mixture was partitioned between EtOAc and water, washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification (SiO2, EtOAc/hexanes) afforded the title compound (0.0045 g): MS (ESI) m/z 328 (M+1).
