Reaction Steps

Using a procedure analogous to Example A1, 1-(3-tert-butylisoxazol-5-yl)-3-(5-(8-ethyl-2-(methylthio)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)-2-fluoro-4-methylphenyl)urea (0.16 g, 0.315 mmol) and methylamine were combined to provide 1-(3-tert-butylisoxazol-5-yl)-3-(5-(8-ethyl-2-(methylamino)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)-2-fluoro-4-methylphenyl)urea (62 mg, 20% yield). 1H NMR (400 MHz, DMSO-d6): δ 10.3 (brs, 1H), 8.67 (brs, 1H), 8.61 (brs, 1H), 7.88 (d, J=9 Hz, 1H), 7.80 (brs, 1H), 7.66 (s, 1H), 7.16 (d, J=12 Hz, 1H), 6.00 (s, 1H), 5.73 (s, 1H), 4.34 (br, 2H), 2.89 (d, J=6 Hz, 3H), 2.07 (s, 3H), 1.21 (br, 12H); MS (ESI) m/z: 494.2 (M+H+).
