Reaction Steps

Using a procedure analogous to Example A1, 1-(4-chloro-2-fluoro-5-(8-methyl-2-(methylthio)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)-3-(5-isopropylisoxazol-3-yl)urea (0.113 g, 0.225 mmol) and 2.0M MeNH2/THF (1.12 ml, 2.25 mmol) were combined to afford 1-(4-chloro-2-fluoro-5-(8-methyl-2-(methylamino)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)-3-(5-isopropylisoxazol-3-yl)urea (52 mg, 48% yield) as a faintly yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 9.85 (s, 1H), 8.94 (brs, 1H), 8.62 (s, 1H), 8.15 (d, J=8.8 Hz, 1H), 7.88 (brq, J=4.8 Hz, 1H), 7.77 (s, 1H), 7.58 (d, J=10.8 Hz, 1H), 6.46 (s, 1H), 3.59 (s, 3H), 3.00 (septet, J=6.8 Hz, 1H), 2.91 (d, J=4.8 Hz, 3H), 1.20 (d, J=6.8 Hz, 6H); MS (ESI) m/z: 486.2 (M+H+), 488.3 (M+2+H+).
