실험 절차

4-(4-Ethyl-piperazin-1-yl)-benzoic acid methyl ester (15 mmol) is dissolved in 4N HCl (35 ml) and heated under reflux for 8 hours. The mixture is cooled in an ice bath to 0-4° C. and the solid material formed is filtered off, washed with acetone and dried (vacuum). A grey powder with mp. >270° C., Rf=0.08 (CH2Cl2/MeOH=9:1) is obtained.
