8-Cyclohexyl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester → 8-Cyclohexyl-2-{4-[2-(morpholine-4-sulfonyl)-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-(morpholine-4-sulfonyl)-ethyl]-phenylamine (from Example 35(A), 75 mg, 0.28 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), 100 mg, 0.26 mmol). The title compound was obtained as a yellow solid (57 mg, 38%). 1H NMR (400 MHz, CDCl3) δ (ppm): 9.26 (s, 1H), 8.46 (s, 1H), 7.65 (br, 1H), 7.55 (d, J=8.4 Hz, 2H), 7.19 (d, J=8.4 Hz, 2H), 5.04 (m, 1H), 4.32 (q, J=7.1 Hz, 2H), 3.68 (m, 4H), 3.22 (m, 4H), 3.10 (m, 4H), 2.00 (m, 4H), 1.80 (m, 1H), 1.62 (m, 2H), 1.48 (m, 2H), 1.34 (t, J=7.1 Hz, 3H), 1.31(m, 1H).
