実験手順
The title compound was prepared from 0.5007 g of 6-(2,3-dimethyl-phenyl)-pyrido[2,3-d]pyrimidine-2,7-diamine from Example 92 and 0.23 mL tert-butyl isocyanate according to Example 2. The product was purified by MPLC eluting with a gradient of CHCl3 :EtOAc (2:1) to CHCl3 :EtOAc (1:1); mp 326-330° C., MS(CI)
