该中间体在本合成路线中的序号：(IV)

In an alternative method, 4-(4-methoxyphenyl)butyric acid (I) is demethylated to phenol (II) by heating at 190 C with pyridine hydrochloride. Alkylation of phenol (II) with ethyl 2-bromoisobutyrate (III) gives ether (IV). The carboxyl group of (IV) is then activated as the corresponding acid chloride (V) by treatment with oxalyl chloride in the presence of DMF.
