Reaction Steps

To 1-(5,6-dichloro-1H-benzoimidazol-2-yl)-2,2,2-trifluoro-ethanone (595 mg) in THF (5 mL) at −78° C. was added phenyl magnesium bromide (4.6 mL of 1 M in THF) dropwise. The resulting mixture was stirred at 0° C. for 4 hr. The reaction was quenched with H2O and 1 N HCl, extracted with EtOAc, dried over Na2SO4, filtered, and concentrated to a residue. The residue was purified by flash chromatography with Biotage 40s+ column and elution with 10%-40% EtOAc/hexanes to yield a yellow solid. The yellow solid was dissolved in a minimal amount of CH2Cl2 and triturated with hexanes to yield the title compound as a tan solid.
