Coupling of taxane intermediate (XIII) with benzyloxyacetic acid (XXI) in the presence of DCC and DMAP provided ester (XXII). After hydrogenolytic deprotection of the benzyl group of (XXII), the resulting hydroxyacetate ester (XXIII) was further condensed with N-carbobenzoxy-L-aspartic acid 1-amide (XXIV) to yield (XXV). Deprotection of the trichloroethoxycarbonyl groups of (XXV) with Zn and AcOH gave (XXVI). Finally, hydrogenolytic cleavage of the N-carbobenzoxy group of (XXVI) in the presence of p-toluenesulfonic acid furnished the title compound.
