METHOD OF OBTAINING DIURIDINTHE TREAPHOSPHATE OR ITS SALT |
| abstract |
The present invention discloses a method for producing P, P-di (uridine 5 ′ -) tetraphosphate (UP) or a salt thereof from UMF serving as a starting material, and using DPC and PF, comprising at least one of the following processing steps: ( a) the addition of UMF diphenyl phosphate (UMF-DFF) in separate portions during the stage of interaction of UMF-DFF with a salt of PF-organic alkali; (b) conducting a reaction step of UMF-DFF with a salt of PF-organic alkali in the presence of a base; and (c) further processing of the synthesized UP alkali. The method for producing UP or its salts in accordance with the invention is carried out in high yield and makes possible large-scale synthesis. |
