Some regularities of the synthesis of ethyl 3-aryl-1,2,4-oxadiazole-5-carboxylates
摘要:
Features of amidoximes reactions with ethyl chlorooxalate in a wide range of solvents at the use of a number of bases were investigated. An efficient preparation method for ethyl 3-aryl-1,2,4-oxadiazole-5-carboxylates in acetonitrile in the presence of triethylamine was developed.
