I am not pretty sure about the following route:
1. nitration, HNO3/H2SO4==> get nitrobenzene
2. chlorination, AlCl3/Cl2 ==> get meta chloro
3. bromination, FeBr3/Br2 ==> get meta bromo
4. lithiation/electrophile external quench, n-BuLi/CH3I ==> replace Br by CH3 (But this is arguable because n-Butyllithium usually not applied to nitro-sub. aromatics)
You may change this step to Grignard.
5. Reduction of NO2, tons of methods available such as H2/Pd, hydrazine hydrate with Pd/C....
