Participants

Reaction Steps

Using a procedure analogous to Example A2, the sulfide was oxidized with mCPBA to the sulfone and then treated with methylamine to provide 1-(3-tert-butyl-1-(quinolin-6-yl)-1H-pyrazol-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. 1H NMR (400 MHz, DMSO-d6): δ 8.95 (m, 2H), 8.48 (m, 1H); 8.15 (m, 1H), 8.04 (d, J=8 Hz, 1H), 7.92 (m, 2H), 7.60 (dd, J=8, Hz, 1H), 7.17 (d, J=12 Hz, 1H), 7.02 (m, 1H), 6.46 (s, 1H), 4.53 (d, J=14 Hz, 1H), 4.33 (d, J=14 Hz, 1H), 3.25 brs, 3H), 2.78 (d, J=5 Hz, 3H), 2.04 (s, 3H), 1.28 (s, 9H); MS (ESI) m/z 609.2 (M+H+).
