Pthalamide on treatment with ethanolic potassium hydroxide forms potassium salt of phthalimide which on heating with alkyl halide followed by alkaline hydrolysis produces the corresponding amine. This reaction is known as:
The following dihaloalkanes gives an N-(haloalkyl)phthalimide on reaction with one equivalent of the potassium salt of phthalimide. Deduce the structure of the phthalimide derivative formed:
