실험 절차

Step G2. The mixture of 3-bromo-5-chlorotoluene (9 g, 43.8 mmol), NBS (8.19 g, 46 mmol), and AIBN (200 mg) in carbon tetrachloride (50 mL) was heated at 80° C. for 3 hours. The resulting mixture was run through a silicon gel column with dichloromethane as the eluant. The fraction was collected and solvent was removed by rotovap, crude 1-bromo-3-(bromomethyl)-5-chlorobenzene (3) was obtained as a brown residue and used in the next step without further purification.
