该中间体在本合成路线中的序号：(VII)Catalytic hydrogenation of 3,5-di-tert-butyl-4-hydroxycinnamic acid (I) afforded the saturated carboxylic acid (II), which was converted into amide (IV) via the corresponding acid chloride (III). Reduction of the amide function of (IV) by means of LiAlH4 furnished the primary amine (V). This was condensed with O-benzyl maltol (VI) to produce the pyridone (VII). After hydrogenolysis of the benzyl protecting group of (VII), the title compound was isolated as the corresponding mesylate salt.
