실험 절차

To a solution of 6-(2,6-dichlorophenyl)-N2 -(4-diethylamino-butyl)-pyrido[2,3-d]pyrimidine-2,7-diamine (1.0 g) from Example 53 in DMF (15 mL) was added one equivalent of 60% sodium hydride suspension (0.93 g). After stirring for approximately 1 hour at room temperature, one equivalent of phenyl isocyanate (0.275 g) was added, and the reaction was monitored by thin layer chromatography. After approximately 24 hours, the solvent was removed in vacuo. The residue was dissolved in ethyl acetate, and this solution was washed several times, first with water and then a saturated solution of sodium chloride. The ethyl acetate layer was dried with magnesium sulfate and concentrated in vacuo. Chromatography of the residue over silica gel using ethyl acetate:methanol: triethylamine (90:10:1) followed by ethyl acetate: ethanol:triethylamine (9:2:1) gave 0.8461 g of the title compound 1-[6-(2,6-dichlorophenyl)-2-(4-diethylamino-butylamino)-pyrido[2,3-d]pyrimidin-7-yl]-3-phenyl-urea, ESMS (20/80 MeOH/CH3CN+0.1% AcOH): M+ +H=552 (Base), 433; mp 81°-87.5° C.
