该中间体在本合成路线中的序号：(XV)Intermediate benzamide (XVI): The sulfonation of 3-hydroxybenzoic acid (XII) with SO3/H2SO4 gives 3-hydroxy-4-sulfobenzoic acid (XIII), which is methylated by means of Me2SO4 and KOH to yield the methoxybenzoic acid (XIV). The reaction of (XIV) with PCl5 affords the dichloride (XV), which is finally treated with tert-butylamine and TEA to provide the target benzamide intermediate (XVI).
