Studies on Pyrazines. 13. Chlorination of 1-Hydroxy-2(1H)-pyrazinones with Phosphoryl Chloride. Formation of 2,5-Dichloro-3-phenylpyrazine from 1-Hydroxy-3-phenyl-2(1H)-pyrazinone
The chlorination of 1-hydroxy-3-phenyl-2(1H)-pyrazinone with phosphoryl chloride proceeded to 5-chloro-3-phenyl-2(H)-pyrazinone or 2,5-dichloro-3-phenylpyrazine on heating to elevated temperatures.To define the mechanism of the novel formation, reactions
