No, it is not used in the reaction.

Answer 2

Answer:

Phthalimide is used as a precursor to anthranilic acid, an azo dyes precursor and saccharin. Alkyl phthalimides are useful precursors to amines in chemical synthesis, particularly in peptide synthesis where they are used to “block both hydrogens and prevent substrates from being racemised.”
