Several 5,7-diaryl-4,5-dihydro-5-methyl-1,2,4-triazolo[1,5-a]pyrimidines 3a-f and 5,7-diaryl-4,7-dihydro-7-methyl-1,2,4-triazolo[1,5-a]pyrimidines 4a-f were synthesized in high yield from 5-amino-1H-1,2,4-triazole (amitrole) (1) and acetophenones 2 by heating in the presence of zinc chloride and subsequent separation of the isomers.
通过在氯化锌存在下加热并随后分离异构体,从 5-amino-1H-1、2,4-三唑(金樟脑)(1)和苯乙酮 2 在氯化锌存在下加热,然后分离异构体,高产合成了 4a-f。
