该中间体在本合成路线中的序号：(IV)In a different strategy, the acetamido isophthalamide (I) is treated with boric acid and KOH to form the cyclic diborate tripotassium salt (II). Subsequent condensation of (II) with epichlorohydrin (III) yields the dimeric adduct (IV). The borate groups of (IV) are finally removed upon quenching with diluted HCl.
