To a solution of [5-bromo-1-(3-methyl-butyl)-1H-benzoimidazol-2-yl]-methanol (1.32 g, 4.44 mmol) in DCM (20 mL) was added thionyl chloride (1.06 g, 8.88 mL) at 0° C. The final solution was stirred at 0° C. for 1 h. The solvent was evaporated and the residue triturated with EtOAc and filtered to give 1.42 g (91%) of 5-bromo-2 chloromethyl-1-(3-methyl-butyl)-1H-benzoimidazole as a white solid.
