반응 단계
4-(4-Isopropyl-piperazin-1-yl)-benzoic acid methyl ester (0.9 mmol) is dissolved in 4N HCl (2 ml) and heated under reflux for 7 hours. The mixture is cooled in an ice bath to 0-4° C. and acetone is added. The solid material formed is filtered off, washed with cold acetone and dried (vacuum). A pale-brown powder with mp. >270° C., Rf=0.08 (CH2Cl2/MeOH=9:1) is obtained.
