The condensation of 1-(4-methoxyphenyl)piperazine (I) with ethyl chloroacetate (II) gives the expected condensation product (III), which by treatment with hydrazine in converted into the corresponding hydrazide (IV). The cyclization of (IV) with benzimidate (V) by heating at 180 C affords the triazole (VI), which is finally condensed with 4-fluorobenzyl chloride (VII) by means of NaH in DMF.
