The condensation of 4-chlorophenylsulfonate (I) with 4-bromophenol (II) by means of K2CO3 in hot DMF gives the aryl ether (III), which is condensed with piperazine (IV) by means of Pdo to yield the monosubstituted piperazine (V). Finally, this compound is condensed with the 4-bromophenyltriazolone (VI) by means of K2CO3 in hot DMSO to afford the target disubstituted piperazine
