| Abstract: | 4-ethyl-1-chloroformyl-2,3-dioxopiperazine(EOCP) was prepared from 4-ethyl-2,3-dioxopiperazine by reaction of bis(trichloromethyl) carbonate(triphosgene). 4-ethyl-2,3-dioxo-piperazine carbonyl chloride was extracted by trimethylsilyl ethers. The yield of the object product was 92.28%. The purity of 4-ethyl-2,3-dioxo-piperazine carbonyl chloride was 82.49%. |
