Versuchsvorschrift

6-(2,6-Dichlorophenyl)-N2 -[3-(4-methyl-piperazin-1-yl)-propyl]-pyrido[2,3-d]pyrimidine-2,7-diamine (1.0 g) from Example 36 was reacted with 0.348 g of octyl isocyanate according to the general procedure of Example 21. Chromatography, eluting first with ethyl acetate:methyl alcohol:triethylamine (90:10:1) then switching to ethyl acetate:ethanol:triethylamine (9:2:1) gave 1.011 g of the title compound 1-{6-(2,6-dichlorophenyl)-2-[3-(4-methyl-piperazin-1-yl)-propylamino]-pyrido[2,3-d]-pyrimidin-7-yl}-3-octyl-urea, ESMS (20/80 MeOH/CH3CN+0.1% AcOH): M+ +H=601; mp 54.5°-57.5° C.
