   This is done using nitration reactions.
   
3. Alkylation of Benzene: The next step is the alkylation of benzene to produce methylbenzene.
   This is done using alkylation reactions.
   
4. Hydroxylation of Benzene: The next step is the hydroxylation of benzene to produce phenol.
   This is done using hydroxylation reactions.
   
5. Dehydration of Phenol: The next step is the dehydration of phenol to produce acetone.
   This is done using dehydration reactions.
   
6. Production of Eslicarbazepine: The final step is the production of eslicarbazepine from the intermediate products.
