Organic synthesis: explain question

A student plans to prepare compound X, whose structure contains a benzene ring with both a carboxyl group and an amide group. The proposed route is:

Step 1: methylbenzene is refluxed with acidified potassium manganate(VII). Step 2: the product of Step 1 is treated with an excess of $\ce{NH3}$ under high pressure and heat. Step 3: the product of Step 2 is treated with $\ce{SOCl2}$. Step 4: the product of Step 3 is treated with an excess of $\ce{NH3}$.

Explain why this route would not produce compound X, and state what the actual organic product of each step would be.
