Abstract
( 8S,9R)-(-)-N-benzylcinchonidinium chloride was synthesized in mixed solvent,using DMF and ethyl acetate as mixed solvent,reflux for few hours,white powder was obtained after recrystallization from water,the yield was 85%,and the structure of the product was confirmed by1 H NMR. This method has the advantages of simple operation,mild reaction conditions,high yield and high purity.
