A method for producing a β-enriched protected decitabine comprising:
a) coupling a protected 2-deoxy-ribofuranose with a protected 5-azacytosine in the presence of a catalyst to form a reaction mixture comprising the protected decitabine of formula I; and b) quenching the reaction mixture of step a) with a base. The β-enriched protected decitabine so made may be deprotected to produce a decitabine product in a high yield and purity.
