Document Type and Number:
WIPO Patent Application WO/2019/072005
Kind Code:
A1
Abstract:
The present invention relates to an azacitidine disaccharide impurity, a preparation method therefor and use thereof. A compound of formula III is obtained by reacting a compound represented by formula IV as a start raw material with a tetraacetyl ribose under the catalysis of a Lewis acid, and the compound of formula III is hydrolyzed to obtain a compound of formula II. The compound of formula II prepared can be used as a reference for the detection of related materials of azacitidine, and is used for quality control applications of azacitidine and related preparations thereof.
