Abstract:2-Bromo-1,3-Cyclohexanedione(Ⅱ) was prepared with 1,3-Cyclohexanedione(Ⅰ) as the initial reactant that was brominated via bromine in aqueous phase.Further more,2-amino-5,6-dihydrobenzod]thiazol-7(4H)-one(Ⅲ) was prepared by the six-hour reflux reaction of Bromo-1,3-Cyclohexanedione(II) and thiourea in ethanol medium at 80 ℃.The yield was 74%.The synthetic products were purified through re-crystallization.Finally,the structure of these products was characterized by 1HNMR.
Keywords:1  3-Cyclohexanedione  bromination  2-Amino-thiazole  synthesis
