该中间体在本合成路线中的序号：(XV)2) Alternatively, N10-formyl-4-amino-4-deoxypteroic acid (VII), prepared as before, was converted to the mixed anhydride (XV) with isobutyl chloroformate and triethylamine, and subsequently condensed with the Na,O-bis(trimethylsilyl) derivative of Nd-phthaloyl-L-ornithine (XVI) to give amide (XVII). Then, hydrolysis of the formamide function and concomitant phthalimide ring opening with aqueous NaOH provided the target compound.
