摘要
An efficient one-pot synthesis of 5-(trifluoromethyl)-4,7-dihydro-7-aryl-[1,2,4]triazolo[1,5-a]pyrimidine derivatives was performed via the reaction of aryl aldehyde, 3-amino-l,2,4-triazole and ethyl 4,4,4-trifluoro-3- oxobutanoate or 4,4,4-trifluoro-l-phenylbutane-1,3-dione in ionic liquid. This method has the advantages of short synthetic route, operational simplicities, mild reaction conditions, high yields and eco-friendliness.
