Participants

Reaction Steps

To 5,6-dichloro-2-(2,2,2-trifluoro-ethyl)-1H-benzimidazole (583 mg) in DMF (6 mL) was added potassium carbonate powder (900 mg) and 2-methylbenzyl bromide (1.2 g). The resulting mixture was stirred at room temperature overnight. The reaction mixture was quenched with water, extracted with EtOAc, and dried over Na2SO4. The crude product was purified by silica gel chromatography (10%-40% EtOAc/hexanes), followed by washing solid with hexanes to yield the title compound as a tan solid.
