英文摘要：

A new compound 7- （ 3-amino-3-arylpropanoyl）-3- （ trifluoromethyl）-5,6, 7, 8-tetrahydro-[ 1,2, 4 ] triazolo [ 4, 3-α ] piperazine was synthesized from 2-chloropyrazine and 3-amino-3- arylpropionic acids through a series of reactions including hydrazinolysis, trifluoroacetylation, cyclization, hydrogenation, condensation and deprotection. The structure of the title compound was characterized by IR, ^1HNMR,^13CNMR and MS.
