| titleOfInvention | Method of 1-(3,5-di-o-benzoyl-2-chloro-2-deoxy-beta-d-threo-pentafuranosile)thymine preparation |
| abstract | The solution falls within the branch of preparation of pharmaceutical intermediary products. It solves a technical problem of economically advantageous production of 1-(3,5-di-0-benzoyl)-2-chlor-2-deoxy-β-D-threo-pentafuranosyl)thymine, which is the raw matter of production of 3-azido-2',3'-dideoxythimidine (AZT). The principle of the preparation procedure according to the solution consists in the fact that 1-(β-D-xylofuranosyl)thymine, obtainable from D-xylose, is across 3',5'-0-isopropylidene derivative gradually transformed to 3',5'-di-0-benzoyl-2,2'-anhydronucleoside, by whose reaction with hydrogen chloride the related compound in high overall yield and high purity is finally obtained. |
