4-(2-Morpholinoethyl)aniline → 8-Cyclohexyl-2-[4-(2-morpholin-4-yl-ethyl)-phenylamino]-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester

Participants

Reaction Steps

Using the procedure outlined in Example 1(g) the title compound was prepared from 4-(2-morpholin-4-yl-ethyl)-phenylamine (from Example 27(A), 54 mg, 0.26 mmol) and 8-cyclohexyl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (from Example 17(e) above, 100 mg, 0.26 mmol). The title compound was obtained as a white solid (77 mg, 59%). 1H NMR (400 MHz, CDCl3) δ (ppm): 9.28 (s, 1H), 8.46 (s, 1H), 7.98 (br, 1H), 7.50 (d, J=8.5 Hz, 2H), 7.17 (d, J=8.5 Hz, 2H), 5.04 (m, 1H), 4.32 (q, J=7.1 Hz, 2H), 3.67 (t, J=4.6 Hz, 4H), 2.76 (m, 2H), 2.54 (m, 2H), 2.47 (m, 4H), 1.99 (m, 4H), 1.78 (m, 1H), 1.61 (m, 2H), 1.46 (m, 2H), 1.34 (t, J=7.1 Hz, 3H), 1.23 (m, 1H).
