Versuchsvorschrift

When the reaction is complete, the salt is filtered off, the solvent is evaporated and the residue is taken up in ether, washed with water and dried over MgSO4. After evaporation of the ether, the oily residue is chromatographed on 120 g of silica, using the system CH2Cl2 /CH3OH (92/8) as eluant. After evaporation of the eluate, the recovered base is converted into the difumarate in ethanol to yield, ultimately, 7.7 g of 2,4-diallylamino-6-{2-[4-(10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl)piperazin-1-yl]ethylamino}-1,3,5-triazine difumarate crystals melting (cap) at 123°-128° C. The aminoethylpiperazine starting material was prepared by reducing the corresponding cyanomethyl compound, [m.p. (cap): 112°-113° C.] with H2 /Ni, in ethanol, in the presence of NH3.
