该中间体在本合成路线中的序号：(III)

Reduction of 3-(3,5-di-t-butyl-4-hydroxyphenyl)propionic acid (I) with LiAlH4 afforded alcohol (II), which was further brominated to (III) using PBr3. Alkylation of p-nitrophenol (IV) by the alkyl bromide (III) gave ether (V). Then, reduction of the nitro group of (V) to the aniline (VI) was accomplished by means of hydrazine in the presence of Raney nickel.
