Objective:To design a method for synthesizing 1,2,3,4-tetrahydro-1-naphthalenamine hydrochloride,which is an impor-tant intermediate for monoamine oxidase(MAO) inhibitors. Methods:1,2,3,4-tetrahydro-1-naphthylamine hydrochloride(11) was synthesized from benzene via acylation,reduction,cyclization,condensation,reduction,and salification by methods of Fridel Crafts acylation,Wolf-kishner-HUANG Minglong reduction and Harwoth cyclization. Results:Overall yield for synthesizing 1,2,3,4-te-trahydro-1-naphthylamine hydrochloride(11) was 43.6%. Conclusions:Method for synthesizing 1,2,3,4-tetrahydro-1-naphthale-namine hydrochloride is establish. Optimized synthetic route has advantages in industrial production for its cheap and readily available raw materials,easy in operation,high yield and high quality of products.
