Chapter 23, Problem 23.84P

Interpretation Introduction

Interpretation:

The given synthesis is to be carried out.

Concept introduction:

Retro synthesis is carried out. If we see the target compound, it is a bromination product. So we undo the bromination. Starting molecule has $\text{NH}\text{-}$ group; therefore further undo the substitution and diazotisation to get the $\text{NH}\text{-}$ group at the place of $\text{Br}$. The synthesis is then carried out with necessary reagents.
