    摘要: A process for making a capecitabine or its derivative comprising (a) reacting a compound of the formula (II): wherein each of R1 and R2 independently represents a hydroxyl protecting group, with an acylating agent of formula (III): X—C(═O)—R3, wherein X is an acyl activating group in an organic solvent to produce an acylated compound; (b) deprotecting the acylated compound to obtain the compound of formula (I); and (c) purifying the compound of formula (I) with a solvent.
