Reaction Steps

1H-Benzoimidazol-2-ylamine (1 g, 7.5 mmol) was dissolved in acetone (30 mL) and powdered potassium hydroxide (2.12 g, 37.5 mmol) was added. The reaction was allowed to stir for several minutes at room temperature before (3-bromopropoxy)(tert-butyl)dimethylsilane (1.75 mL, 7.5 mmol) was added. After 1 hour, methylene chloride was added and the mixture was washed with water, brine and dried over magnesium sulfate. Upon concentration the crude product was dissolved in methylene chloride and purified by combiflash chromatography, methylene chloride to methylene chloride 6% MeOH gradient, to give 1-(3-(tert-butyldimethylsilyloxy)propyl)-1H-benzo[d]imidazol-2-amine (0.400 g, 1.3 mmol).
