उत्तर
This method is used for the synthesis of primary amine. It involves the following three stages.
i. Formation of the potassium salt of phthalimide from phthalimide on reaction with alcoholic potassium hydroxide.
ii. Formation of N-alkyl phthalimide from the potassium salt by reaction with an alkyl halide.
iii. Alkaline hydrolysis of N-alkyl phthalimide to form the corresponding primary amine.
