Versuchsvorschrift
A mixture of 8.5 g (0.05 mole) of a n-hexyl piperazine and 6.8 g (0.056 mole) of 1-chloro-3-pentanone was heated to 140° for 5 minutes. The reaction product was dissolved in isopropanol and acidified with a solution of HCl in isopropanol. The dihydrochloride salt was filtered and crystallized from acetonitrile to give 11.0 g of white solid with a melting point of 230°-233° C.
