Friedel-Crafts acylation of 3-methoxyphenol (I) with 4-hydroxyphenylacetic acid (II) in the presence of ZnCl2 and POCl3 furnished ketone (III), which was subsequently protected with triisopropylsilyl chloride and Et3N to yield the mono-silyl ether (IV). Coumarin (VI) was then synthesized by condensation of hydroxy ketone (IV) with phenylacetyl chloride (V) in the presence of K2CO3. Alkylation of the phenolic hydroxyl group of (VI) with N-(2-chloroethyl)piperidine (VII) gave the piperidinylethyl ether (VIII). Finally, selective methyl ether hydrolysis using HBr in refluxing HOAc led to the title compound.
