Versuchsvorschrift

To 1-chloro-2-(5,6-dichloro-1-methyl-1H-benzoimidazol-2-yl)-propan-2-ol (408 mg) in methanol (10 mL) at room temperature was added a solution of 2-methyl-1-propanethiol (150 mg) and sodium methoxide (0.381 mls of 25 wt % in MeOH). The resulting mixture was stirred at room temperature overnight. The reaction mixture was then concentrated. The crude product was purified by flash chromatography (10%-40% EtOAc/hexanes) to yield the title compound as a light orange solid.
