| YANG Yi hong; etc （Wuhan Institute of Chemical Technology; Wuhan Hubei 430073; China） |
| Abstract：4-Bromoethyl 2(H) quinolinone was synthesized by the acylation of aniline with biketene in toluene, the bromination in chloroform, and the cyclization in sulfuric acid. The result shows that the overall yield is 60.36% and content up to 98.6%. The raw material can be gotten easily using the method. The operating process is simple, and the yield is high. |
| Key words：2（H）-quinolinone; bromination; cyclization; synthesis |
