Reaction Steps

To a solution of 2-(6-methoxy-1H-benzo[d]imidazol-1-yl)ethanol (200 mg, 1.04 mmol) in DCM (6.0 mL), CBr4 (397 mg, 1.20 mmol) was added, then the reaction mixture was cooled to 0° C. and PPh3 (314 mg, 1.20 mmol) was added. After stirring at rt for 2 h the solvent was removed under reduced pressure to yield the title compound as a brown oil, which was used us such in the next step. LC-MS conditions B: tR=0.42 min, [M(79Br)+H]+=255.08.
