Starting with both compounds dissolved in the dichloromethane, use a separatory funnel to extract with a very dilute aqueous acid. This will dissolve the p-cresol (about 2 grams per 100 mL), but very little of the p-bromobenzoic acid. Repeat several times.
Perhaps the classical method would be to extract the dichloromethane solution with dilute Bicarbonate (HCO3-) solution. Perhaps do this twice. This should dissolve the p-bromobenzoic acid, but very little of the p-cresol. The bicarbonate extract can then be neutralized with acid and extracted into clean dichloromethane.

Hi, do you need a flowchart in doing so? Is this for CM1501?
