Coupling between phenol derivative (I) and 1-bromo-4-chlorobutane (II) by means of either Na2CO3/NaI or K2CO3 in refluxing 5-methyl-2-hexanone affords 4-chlorobutoxy derivative (III), which is then converted into the desired product by condensation with (2-methoxyphenyl)piperazine dihydrochloride (IV), either by means of Na2CO3/NaI or with K2CO3 in refluxing 5-methyl-2-hexanone.
