Reaction Steps

BBr3 (26 mL; 0.275 mmol) was added to a solution of chloro-3,5-dimethyoxybenzene (10 g; 30 mmol) in CH2Cl2 (100 mL) at −70° C. The cooling bath was removed and the solution was stirred at room temperature for 4 days. After re-cooling to −70° C., MeOH was added (150 mL). After evaporation of the solvent, toluene was added and removed in vacuo. Purification by kugelrohr distillation afforded 9 g (100%) of the sub-title compound.
