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 0.186 g of allyl isocyanate according to the general procedure of Example 37. The product was purified by chromatography and crystallized from ethyl acetate to give 0.31 g of 1-allyl-3-{6-(2,6-dichlorophenyl)-2-[3-(4-methyl-piperazin-1-yl)-propylamino]-pyrido[2,3-d]pyrimidin-7-yl}-urea, ESMS (20/80 MeOH/CH3CN+0.1% AcOH): M+ +H=529 (Base), 472, 446; mp 104°-108° C.
