The alkylation of ammonia, Gabriel synthesis, reduction of nitriles, reduction of amides, reduction of nitrocompounds, and reductive amination of aldehydes and ketones are methods commonly used for preparing amines. The reaction of ammonia with an alkyl halide leads to the formation of a primary amine.

The primary amine that is formed can also. Heterocyclic chemistry is the most complex and intriguing branch of organic chemistry, and heterocyclic compounds constitute the largest and most unique family of organic compounds [1, 2, 3].Nitrogen, oxygen, and sulfur are the most common heteroatoms but some other heterocyclic compounds containing selenium, tellurium, phosphorus, arsenic, silicon, boron, etc., are also widely : Warjeet S.
