Propose a step-by-step microscale extraction procedure that could be used to separate a mixture nitrobenzene, 4-methoxybenzoic acid, and benzylamine into the pure compounds using extraction technique. All of the molecules are organic-soluble in dichloromethane. Show a flow chart with all steps (solvents, drying agents, layer labels) that you will need to do to get the three compounds in pure form.
