该中间体在本合成路线中的序号：(VI)The reaction of 5-aminoisophthalic acid (I) with 1,8-naphthalic anhydride (II) in DMSO/pyridine gives the expected naphthalimide (III), which is condensed with diethylenetriamine (IV) by means of CDI in DMA to yield the isophthalamide (V). Finally, the free amino groups of (V) are condensed with 4-chloronaphthalic anhydride (VI) in pyridine/DMSO to afford the target tris naphthalimide.
