摘要
研究了5-溴-3-仲丁基-6-甲基脲嘧啶(除草定)的新合成方法.以2-溴丁烷和尿素作为起始原料,经缩合、环化、溴代三步反应得到除草定,总收率为61%.用1HNMR,13CNMR,IR对产物结构进行了表征.
A new synthetic method of 5-bromo-3-sec-butyl-6-methyluracil(Bromacil) was described. Bromacil was synthesized using 2-bromobutane and urea as the starting materials in three steps including condensation, cyclization and bromination with to-tal yield of 61%. The structure of Bromacil was characterized by ^1HNMR, ^13CNMR and IR.
