Chemical Properties

White Powder

Uses

2,6-Dichloropyrazine is used in the preparation of pyrazine and pyridine compounds as ATR kinase inhibitors. It is also used in the synthesis of oxacalixarenes containing nitrogen heterocycles.

Synthesis

The production method of 2,6-dichloropyrazine comprises the following steps: carrying out ammoniation and cyclization reactions of raw materials comprising methyl chloroacetate, glyoxal and the like to prepare 2-hydroxypyrazine sodium, reacting 2-hydroxypyrazine sodium with phosphorous oxychloride under the catalysis action of N,N-dimethylaminopyridine to prepare 2-chloropyrazine, and chlorinating 2-chloropyrazine by chlorine under the catalysis action of triethylamine with dimethyl formamide as a solvent to prepare 2,6-dichloropyrazine.
