Versuchsvorschrift

A mixture of N-[amino(methylamino)methyl]-2,6-dichloro-benzeneacetamide (4.15 g) and intermediate 6 (3.05 g) in DMF (25 ml) was stirred and refluxed for 20 hours. The solvent was evaporated, the residue dissolved in DMF (25 ml) and heated at 80° C. for 16 hours and at 100-108° C. for another 66 hours. The reaction mixture was cooled, quenched with water, extracted with diethyl ether, and washed with dilute NaOH, water, brine, and dried over K2CO3. The solvent was evaporated, and the residue was purified by flash column chromatography, and recrystallized from 2-propanol, and finally from methanol, yielding 0.78 g (12.6%) of 4-[[4-[(2,6-dichlorophenyl)methyl]-6-(methyl-amino)-1,3,5-triazin-2-yl]amino]benzonitrile (compound 7, mp. 229-230° C.).
