Explanation:
Since the -CH3CN and the -F are in 1,4 position, then the synthesis started with flourobenzene. This has to be because -F is ortho-para directing in nucleophilic substitution.
The next step is the Friedel craft alkylation of the substrate. The alkyl group is directed to the para position by the -F.
Bromination using NBS yields an alkyl bromide that undergoes SN2 substitution to yield the target compound.
