英文摘要：

The compound, 2, 3, 6 -triphenylpyridine, was synthesized by catalytic heterocyclization from phe- nylmethanamine and ethynylbenzene using hydrophilie （NH2CH2COOH）2PdC12 as catalyst and K2CO3, AgNO3 as cocatalyst in DMF. The structure of the target complex was characterized by 1H NMR and^13C NMR. The optimal conditions of base, reaction temperature, catalyst loading and reaction time were investigated. The separate yield of the target compound was 57% under the optimal conditions.
