Versuchsvorschrift

To a solution of 1-hydroxybenzotriazole (5.35 g) and 4-[4-(4-hexyloxyphenyl)piperazin-1-yl]benzoic acid hydrochloride (15 g) in the mixture of triethylamine (9.64 ml) and dichloromethane (450 ml) was added 1-ethyl-3-(3′-dimethylaminopropyl) carbodiimide hydrochloride (WSCD.HCl) (12.6 g) and stirred for 4 hours at ambient temperature. The reaction mixture was added to water. The organic layer was taken and dried over magnesium sulfate. Magnesium sulfate was filtered off, and the filtrate was evaporated under reduced pressure to give 1-[4-[4-(4-hexyloxyphenyl)piperazin-1-yl]benzoyloxy]benzotriazole (16.78 g).
