The condensation between aldehyde (VII), piperazine (III) and benzotriazole furnished adduct (VIII). The Grignard reagent (X), prepared by silylation of 3-bromophenol (IX) followed by reaction with Mg, was then condensed with the benzotriazolyl adduct (VIII) to give the (diarylmethyl)piperazine (XI). Finally, basic hydrolysis of the ethyl ester of (XI) yielded the title compound.
