Participants

Reaction Steps

1-(5,6-DiChloro-1H-benzoimidazol-2-yl)-2,2,2-trifluoro-ethanone (503 mg), 3-chloro-1,2-propan-diol (393 mg) and potassium carbonate (491 mg) were dissolved in DMF (5 mL). The reaction mixture was stirred for 18 hrs at ambient temperature, then diluted with ethyl acetate (50 mL), washed with water (50 mL) and brine (2×20 mL). The extracts were dried over Na2SO4, filtered, concentrated, and purified by column chromatography (SiO2; 40% ethyl acetate/hexanes), followed by washing solid with CH2Cl2/hexanes to yield the title compound as an off-white solid.
