Method for synthesizing 2-(1-cyclohexenyl)ethylamine

A method for synthesizing 2-(1-cyclohexenyl)ethylamine. Cyclohexanone (II) is reacted with a Grignard reagent in a first organic solvent to produce 1-vinylcyclohexanol (III), which is then subjected to chlorination and rearrangement reaction with a chlorinating reagent in a second organic solvent in the presence of an organic base to synthesize (2-chloroethylmethylene)cyclolxane (IV). Then (2-chloroethylmethylene)cyclohexane (IV) and urotropine are subjected to quaternization in a third organic solvent to synthesize N-cyclohexylidene ethyl urotropine hydrochloride (V). Finally, the N-cyclohexylidene ethyl urotropine hydrochloride (V) undergoes hydrolysis and rearrangement reaction in a solvent in the presence of an inorganic mineral acid to synthesize 2-(1-cyclohexenyl)ethylamine (I).
