| titleOfInvention | A kind of method preparing the Decitabine precursor of β-enrichment |
| abstract | The invention discloses a kind of method preparing the Decitabine precursor of β-enrichment, by the Decitabine precursor crude product of isomer α/β=1/0.8 ~ 2, reflux in the mixed solvent that water and organic solvent C1-C3 alcohol, acetone or tetrahydrofuran (THF) form, cooling, filtration, filtrate is concentrated, crystallization, filtration, filter cake vacuum-drying, obtains the Decitabine precursor of β-enrichment, its isomer α/β=1/7 ~ 18.After the Decitabine precursor deprotection base of gained β-enrichment, obtain high yield, highly purified Decitabine. |
