Step 1: Initial reaction with acetic acid.
In the first step, the methyl group ( ) undergoes oxidation with acetic acid, forming an intermediate compound where the amino group ( ) remains attached to the benzene ring. This is a Friedel-Crafts type alkylation.
Step 2: Oxidation with KMnO .
The second step involves oxidation using alkaline KMnO . Potassium permanganate is a strong oxidizer that will oxidize the methyl group ( ) into a carboxyl group ( ).
Step 3: Final acidification.
The final step involves acidification with dilute , which helps to stabilize the carboxyl group formed during oxidation.
Conclusion:
The product is a carboxylated intermediate ( ), and the final product is the carboxylated compound with a carboxylic acid group.
