Procedure
Using the procedure outlined in Example 1(g) the title compound was prepared from 2-(4-amino-phenyl)-ethanesulfonic acid isopropylamide (from Example 33(B), 68 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 (50 mg, 35%). 1H NMR (400 MHz, CDCl3) δ (ppm): 9.34 (s, 1H), 8.54 (s, 1H), 7.88 (br, 1H), 7.61 (d, J=8.3 Hz, 2H), 7.25 (d, J=8.3 Hz, 2H), 5.10 (m, 1H), 4.40 (q, J=7.1 Hz, 2H), 4.17 (m, 1H), 3.66 (m, 1H), 3.29 (m, 2H), 3.14 (m, 2H), 2.06 (m, 4H), 1.86 (m, 1H), 1.68 (m, 2H), 1.51 (m, 2H), 1.41 (t, J=7.1 Hz, 3H), 1.31(m, 1H), 1.24 (s, 3H), 1.23 (s, 3H).
