Abstract:(S)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline was prepared through a series of reactions including benzoylation, dehydration cyclization, reduction and resolution with D-tartaric acid using phenylethylamine as a starting material. The purity of the target product was of 99.5 %, the overall yield was of 76.3%. The structure of (S)-1-Phenyl-1,2,3,4- tetrahydroisoquinoline was confirmed by melting point, MS and 1H NMR. This process has many advantages including simple in operation, without special equipment requirements, and suitable for industrial production.
