The condensation of ethyl p-hydroxyphenylacetate (I) with benzyl chloride (II) by means of sodium ethoxide in refluxing ethanol gives ethyl p-(benzyloxy)phenylacetate (III), which is reduced with LiAlH4 in THF to 2-(p-benzyloxyphenyl)ethanol (IV). The etherification of (IV) with cyclopropyl bromide (A) by means of NaH in hot DMF affords 4-(cyclopropylmethoxyethyl)-1-benzyloxybenzene (V), which is debenzylated by hydrogenation with H2 and Pd/C in methanol giving rise to p-(cyclopropylmethoxyethyl)phenol (VI). The condensation of (VI) with epichlorohydrin (B) by means of NaOH in water yields 1-[p-(cyclopropylmethoxyethyl)phenoxy]-2,3-epoxypropane (VII), which is treated with isopropylamine (C) and finally with HCl in ether.
