The process includes oxidation with KMnO4, chlorination with SOCl2, amination with NH3, and finally bromination with Br2 in the presence of FeBr3. The key to solving the problem lies in understanding the regioselectivity of the bromination step, which results in the formation of 3-bromo-benzamide as product D."}
