実験手順

To a solution of 3-[1-piperazinyl]biphenyl (11.9 g) in aceonitrile (200 cc), there is added potassium carbonate (6.9 g) and then, in the course of 20 minutes, a solution of α-chloro-p-xylene (8 g) in acetonitrile (50 cc), at a temperature in the region of 20° C., and stirring is continued for 16 hours. The insoluble material which has formed is separated by filtration. The solution obtained is concentrated under reduced pressure (20 mm Hg; 2.7 kPa) at 40° C. The residue is dissolved in methylene chloride (30 cc) and the solution poured onto silica (1 kg) contained in a column 8 cm in diameter. Elution is performed with a mixture (3 liters) of methylene chloride and methanol (97.5:2.5 by volume) and the corresponding eluate is concentrated to dryness under reduced pressure (20 mm Hg; 2.7 kPa) at 50° C. The residue obtained is dissolved in acetone (600 cc). The solution is cooled to a temperature in the region of 5° C., 2.5N ethereal hydrogen chloride (40 cc) is added and stirring is maintained for approximately 1 hour. The precipitate formed is separated by filtration and washed with acetone (2×40 cc). 3-[4-(4-Methylbenzyl)-1-piperzinyl]biphenyl dihydrochloride (17.3 g), m.p. 241° C., is thereby obtained.
