Reaction Steps
Nitriles were reacted with LiHMDS or KHMDS to benzamidines which were converted to triazole by melting with hydrazides. The triazoles were coupled with 2-bromoacetic acid methyl ester under basic conditions to give the desired triazole-1-yl-acetic acid methyl ester together with different quantities of the isomeric systhem. The triazole-1-yl-acetic acid methyl ester was hydrolyzed with LiOH to the coresponding acid. The isomeres were either seperated before ore after hydrolysis of the ester. Finally, the triazole-1-yl-acetic acides were coupled with aryl substituted piperazines to the desired products.
