Reaction Steps

Using a procedure analogous to Example A1, 1-(1-tert-butyl-1H-pyrazol-4-yl)-3-(2-fluoro-4-methyl-5-(8-methyl-2-(methylthio)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)urea (0.192 g, 0.39 mmol) and 2M methylamine in THF (1 mL; 5 eq) were combined to afford 1-(1-tert-butyl-1H-pyrazol-4-yl)-3-(2-fluoro-4-methyl-5-(8-methyl-2-(methylamino)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)urea as an off-white solid (0.174 g, 94% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.63 (s, 1H), 8.60 (s, 1H), 8.40 (d, J=1.6 Hz, 1H), 7.94 (d, J=8.8 Hz, 1H), 7.80-7.77 (m, 2H), 7.66 (s, 1H), 7.36 (s, 1H), 7.10 (d, J=8.4 Hz, 1H), 3.59-3.51 (m, 3H), 2.90 (d, J=4.4 Hz, 1H), 2.05 (s, 3H), 1.45 (s, 9H); (ESI) m/z: 479.2 (M+H+).
