Answer:

extract the ether solution with aqueous HCl and treat the water layer with aqueous NaOH.

Explanation:

p-toluidine is a basic compound, it can react with aqueous HCl to form p-Toluidine hydrochloride and is recovered subsequently.

An alkali such as NaOH can be used to recover the p-toluidine. The neutral compound, p-nitrotoluene, will remain in the ether layer and can be recovered by evaporating the solution.
