Participants

Reaction Steps

Using a procedure analogous to Example 57, 1-(3-t-butylisoxazol-5-yl)-3-(2-fluoro-5-(8-methyl-2-(methylsulfinyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)urea from Example 43 (0.150 g, 0.311 mmol, 1.00 eq) and (R)-(+)-alpha-methylbenzylamine (0.0846 ml, 0.656 mmol, 3.00 eq) were combined to afford (R)-1-(3-tert-butylisoxazol-5-yl)-3-(2-fluoro-5-(8-methyl-7-oxo-2-(1-phenylethylamino)-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)urea (51 mg, 42% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 10.34 (s, 1H), 8.73 (brs, 1H), 8.65 (brs, 1H), 8.51 (d, J=7.6 Hz, 1H), 8.37 (d, J=7.6 Hz, 1H), 7.85 (s, 1H), 7.447.38 (m, 2H), 7.31-7.25 (m, 4H), 7.20-7.16 (m, 1H), 6.06 (s, 1H), 5.16-5.09 (m, 1H), 3.48 (s, 3H), 1.48 (d, J=7.2 Hz, 3H), 1.23 (s, 9H); MS (ESI) m/z: 556.3(M+H+).
