Synthesis of 2,3-dichloroquinoxalines via vilsmeier reagent chlorination
A convenient and high-yielding synthesis of 2,3-dichloroquinoxalines from the corresponding 2,3- dihydroxyquinoxalines has been developed. Treatment of a slurry of the 2,3-dihydroxyquinoxaline 1a-j with N,N-dimethylformamide in the presence of excess thionylchloride in 1,2-dichloroethane results in the rapid and high-yielding formation of the 2,3-dichloroquinoxaline derivatives 2a-j. Simplified workup and purification procedures for these compounds are also described.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 2213-63-0, and how the biochemistry of the body works.Reference of 2213-63-0
