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 0.378 g of 1-naphthyl isocyanate according to the general procedure of Example 37. Chromatography, eluting first with ethyl acetate:methyl alcohol:triethylamine (90:10:1) then switching to ethyl acetate:ethanol:triethylamine (9:2:1) gave 0.97 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-naphthalen-1-yl-urea, ESMS (20/80 MeOH/CH3CN+0.1% AcOH): M+ +H=615 (Base), 446; mp 186.5-189° C.
