Reaction Steps

The title compound was synthesized from 4-[2-(3-aminophenyl)pyrazolo[1,5-a]pyridin-3-yl]-N-(3-{[2-(diethylamino)ethyl]oxy}phenyl)-2-pyrimidinamine using acylation with 2-thienylacetyl chloride as described in Example 10, Step E to yield a light brown solid in 49% yield. 1H NMR (400 MHz, DMSO-D6) δ ppm 1.2 (t, J=7.2 Hz, 6H) 3.2 (s, 4H) 3.5 (s, 2H) 3.9 (s, 2H) 4.3 (s, 2H) 6.5 (d, J=5.3 Hz, 1H) 6.6 (s, 1H) 7.0 (m, 2H) 7.1 (d, J=1.5 Hz, 1H) 7.3 (d, J=5.1 Hz, 1H) 7.4 (m, 2H) 7.5 (m, 1H) 7.6 (s, 1H) 7.7 (s, 1H) 7.9 (s, 1H) 8.2 (d, J=5.3 Hz, 1H) 8.5 (s, 1H) 8.8 (d, J=7.0 Hz, 1H) 9.6 (s, 2H) 10.4 (s, 1H).
