Versuchsvorschrift

A solution of N-[2-trifluoromethoxy-5-(4-methyl-piperazin-1-yl)-phenyl]-acetamide (4.75 g, 15 mmol) in EtOH (100 mL) was treated with HCl 37% (35 mL). After 1 h under reflux the mixture was concentrated and tritured with hexane to give in quantitative yield, 5.74 g of 2-trifluoromethoxy-5-(4-methyl-piperazin-1-yl)-phenylamine trihydrochloride salt.
