Procedure

A solution of the product from Example 43D and Pyridin-2-ylamine was reacted to provide 4-(4-Benzyloxy-phenoxy)-3-(7-isopropyl-pyrido[2,3-d]pyrimidin-4-ylamino)-N-pyridin-2-yl-benzamide using the procedure from Example 43E. The material was then deprotected using the procedure from Example 43F to provide the crude title compound which was purified by HPLC with TFA to provide the title compound as a trifluoroacetic acid salt (5 mg, 10%). 1H NMR (300 MHz, DMSO-D6) δ ppm: 1.35 (d, J=6.99 Hz, 6 H) 3.28 (m, 1 H) 6.78 (m, 2 H) 6.87 (d, J=8.82 Hz, 1 H) 6.94 (m, 2 H)7.18 (dd, J=7.35, 4.78 Hz, 1 H) 7.88 (m, 2 H) 8.09 (dd, J=8.46, 2.21 Hz, 1 H) 8.17 (d, J=8.46 Hz, 1 H) 8.22 (d, J=2.21 Hz, 1 H) 8.38 (d, J=2.94 Hz, 1 H) 8.94 (s, 1 H) 9.03 (d, J=8.82 Hz, 1 H) 9.48 (s, 1 H) 10.80 (s, 1 H) 11.61 (s, 1 H); MS (ESI+) m/z 493 (M+H)+.
