该中间体在本合成路线中的序号：(II)Condensation of 4-nitrophthalic anhydride (I) with O-benzyl hydroxylamine in refluxing toluene produced phthalimide (II). Catalytic transfer hydrogenation employing cyclohexene in the presence of Pd/C yielded 4-amino-N-hydroxyphthalimide (III), which was condensed with ethanesulfonyl chloride to give sulfonate (IV). Finally, acylation with acid chloride (V) furnished the title compound.
