Reaction Steps

To a solution of phenyl N-cyano-N′-(2-{[4-(2,4-difluorophenyl)-8-(2-fluorophenyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-2-yl]amino}-ethyl)imidocarbamate in isopropanol (2 mL) was added a 2M solution of ammonia in isopropanol (2 mL). The mixture was irradiated with microwave at about 60° C. for about 20 min. LC/MS showed a mixture containing approximately 25% product and 75% starting material. The mixture was kept in a sealed tube for 6 days. LC/MS showed 100% product. The solvent was evaporated and the residue was purified to give the title compound (20 mg, 60%). LC-MS m/z 479 (M+H)+, 2.84 min (ret time).
