How to prepare a fluorocytidine derivative |
| abstract |
The present invention relates to a method for producing capecitabine and its derivatives, the method comprising (a) reacting a compound of formula (II) with an acylating agent of formula (III) {XC (= O) -R 3 } in an organic solvent to produce an acylated compound, (II) Wherein R 1 and R 2 each independently represent a hydroxy protecting group, X is an acyl activator, (b) deprotecting the acylated compound to obtain a compound of formula (I), (c) purifying the compound of formula (I) with a solvent . |
