Procedure

Using a procedure analogous to Example A1, 1-(2-fluoro-5-(8-methyl-2-(methylthio)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)-3-(3-(trifluoromethyl)phenyl)urea (436 mg, 0.866 mmol) and 2.00N methylamine in THF (1.93 mL, 3.85 mmol) were combined to provide 1-(2-fluoro-5-(8-methyl-2-(methylamino)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)phenyl)-3-(3-(trifluoromethyl)phenyl)urea (141 mg, 75% yield). 1H NMR (300 MHz, DMSO-d6): δ 2.89 (s, 3 H), 3.53-3.61 (m, 3 H), 7.24-7.31 (m, 3 H), 7.49-7.51 (m, 2 H), 7.65-7.75 (br. m, 1 H), 7.79 (m, 1 H), 8.03 (s, 1 H), 8.37-8.39 (m, 1 H), 8.65-8.73 (m, 2 H), 9.40 (s, 1H); MS (ESI) m/z: 487.0 (M+H+).
