Reaction Steps

Using a procedure analogous to Example A2, 1-(3-tert-butylisoxazol-5-yl)-3-(2-fluoro-4-methyl-5-(1-methyl-7-(methylthio)-2-oxo-1,2-dihydropyrimido[4,5-d]pyrimidin-3(4H)-yl)phenyl)urea (0.58 g, 1.2 mmol) and methylamine (1 ml, 3 mmol, 3.0M in THF) were combined to provide 1-(3-tert-butylisoxazol-5-yl)-3-(2-fluoro-4-methyl-5-(1-methyl-7-(methylamino)-2-oxo-1,2-dihydropyrimido[4,5-d]pyrimidin-3(4H)-yl)phenyl)urea (0.995 g, 95% yield). 1H NMR (400 MHz, DMSO-d6): δ 10.31 (brs, 1H), 8.73 (s, 1H), 8.00 (d, J=9 Hz, 1H), 7.94 (brs, 1H), 7.23 (d, J=12 Hz, 1H), 7.02 (m, 1H), 6.04 (s, 1H), 4.55 (d, J=14 Hz, 1H), 4.35 (d, J=14 Hz, 1H), 3.24 (brs, 3H), 2.79 (d, J=5 Hz, 3H), 2.08 (s, 3H), 1.22 (s, 9H); MS (ESI) m/z: 483.3 (M+H+).
