Describe the Gabriel synthesis method for preparing primary amines.

• In the Gabriel synthesis, phthalimide is hydrolyzed to form the primary amine directly.

• Primary amines are obtained in the Gabriel synthesis by reacting phthalimide with a carboxylic acid.

• The Gabriel synthesis method for preparing primary amines involves reacting phthalimide with an alkyl halide, followed by hydrolysis to obtain the primary amine.

• The Gabriel synthesis method involves the direct reaction of an amine with an alkyl halide.
