8-Indan-5-yl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester → 8-Indan-5-yl-2-[4-(2-isopropylsulfamoyl-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 2-(4-amino-phenyl)-ethanesulfonic acid isopropylamide (58 mg, 0.24 mmol) and 8-indan-5-yl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (from Example 1(e) above, 100 mg, 0.24 mmol). The title compound was obtained as a white solid (50 mg, 36%). 1H NMR (400 MHz, CDCl3) δ (ppm): 9.34 (s, 1H), 8.53 (s, 1H), 7.88 (br, 1H), 7.42 (d, J=7.9 Hz, 1H), 7.27 (m, 3H), 7.18 (d, J=7.9 Hz, 1H), 6.94 (br, 2H), 5.88 (s, 1H), 4.37 (q, J=7.1 Hz, 2H), 3.61 (m, 1H), 3.22 (m, 2H), 3.10-2.96 (m, 6H), 2.23 (m, 2H), 1.38 (t, J=7.1 Hz, 3H), 1.25 (s, 3H), 1.22 (s, 3H).
