反応手順
The title compound was prepared from 0.25 g of 6-(2,6-difluoro-phenyl)-pyrido[2,3-d]pyrimidine-2,7-diamine from Example 63 and 0.112 mL of tert-butyl isocyanate according to Example 2. The product was purified by MPLC eluting with a gradient of CHCl3 :EtOAc (1:1) to EtOAc to afford the pure product; mp >300° C., CIMS (1% ammonia in methane): m/z (relative intensity) 373 (MH+ +1, 60), 374 (MH+ +2, 10), 274 (100).
