FIELD: chemistry.
SUBSTANCE: invention applied for relates to process of obtaining 2,6- dichlor-9-(2,3,5-tru-O-acetyl-β-D-ribofuranozyl) purine and may be used in organic chemistry and pharmaceutical industry. The process involves conduction of 2,6- dichlor-9-(2,3,5-tru-O-acetyl-β-D-ribofuranozyl) purine with tret-butyl nitrite in the methylene chloride medium at (-18)-(-22)°C during 2 hours in presence of pyridine hydrochloride and phosphorus oxychloride followed by decomposing the reaction mixture with chipped ice, and cleansing of the target product in methylene chloride with flash-chromatography on silica gel.
EFFECT: obtaining of substance with high grade of purity and high output by simplified technology.
