WebSN1 is out. And so you might think that you can't do a nucleophilic aromatic substitution. But as a matter of fact you can, and let's take a look at the criteria in order to do so. So your ring must have an electron withdrawing group, so withdrawing some electron density from the ring. We have that here, of course. A nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring. Aromatic rings are usually nucleophilic, but some aromatic compounds do undergo nucleophilic substitution. Just as normally nucleophilic alkenes can be made to undergo conjugate substitution if they carry electron-w…
