Reaction Steps

Under Ar, a soln of hydroxylamine hydrochloride (119 mg, 1.72 mmol) and triethylamine (0.26 mL, 1.89 mmol) in 5 mL of DMSO was stirred at room temperature for 5 min, the product of Example 206, 3-[8-(2,6-difluoro-phenyl)-4-(4-fluoro-2-methyl-phenyl)-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-ylamino]-propionitrile (150 mg, 0.34 mmol) was added. The resulting mixture was heated to 80° for 16 h. Preparative hplc, followed by recrystallization from ethanol and hexane, gave the desired product 80 mg (45%). LC-MS: 469.2 (MH+, m/z), 1.52 (Rt, min).
