The condensation of 2-(bromomethyl)-2-(2,4-dichlorophenyl)-4-(benzoyloxymethyl)-1,3-dioxolane (I) with triazole (II) by means of NaH in DMSO, followed by hydrolysis with NaOH in dioxane water gives 2-(2,4-dichlorophenyl)-2-(1H)-1,2,4-triazol-1-ylmethyl)-1,3-dioxolane-4-methanol (III), which is acylated with methanesulfonyl chloride in pyridine affording the corresponding 4-mesyloxymethyldioxolane (IV). Finally, this compound is condensed with 4-(4-isopropylpiperazin-1-yl)phenol (V) by means of NaH in hot DMSO. Compound (V) is obtained as follows: 4-(4-methoxyphenyl)piperazine (VI) is reductocondensed with acetone (A) by means of H2 over Pd/C giving 1-isopropyl-4-(4-methoxyphenyl)piperazine (VII), which is then demethylated with refluxing aqueous 48% HBr yielding (V)
