Reaction Steps

The title compound was prepared from N-{3-[8-(2,6-difluorophenyl)-2-(methylsulfonyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl]-4-methylphenyl}-3-thiophenecarboxamide and 4-piperidinamine according to General Procedure for Sulfoxide/Sulfone Displacement, described above. The concentrated reaction mixture was purified via reversed-phase HPLC to give the desired compound as a light tan powder (0.041 g, 32%). HPLC indicated the material to be >95% pure (m.p. 183.8-187.9): LC-MS m/z 573 (M+H)+, 1.79 min (ret time).
