Reaction Steps

8-Indan-5-yl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (0.098 g, 0.24 mmol) and 4-(4-methyl-piperazin-1-ylmethyl)-phenylamine (0.049 g, 0.24 mmol) were combined in i-PrOH (2 mL) and heated to 90° C. After 3 h, the reaction mixture was concentrated and purified by preparative HPLC (30 mL/min 5-100% MeCN/H2O gradient over 10 min) and lyophilized to provide 20 mg of 8-Indan-5-yl-2-[4-(4-methyl-piperazin-1-ylmethyl)-phenylamino]-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester. 1H NMR (400 MHz, CDCl3) δ (ppm): 9.36 (s, 1H), 8.54 (s, 1H), 7.43 (d, 2H, J=7.9 Hz), 7.29 (m, 2H), 7.18 (dd, 2H, J=2.0 Hz, J=7.9 Hz), 7.03-7.05 (m, 1H), 4.38 (q, 2H, J=7.1 Hz), 3.44 (s, 2H), 3.08 (t, 2H, J=7.4 Hz), 3.01 (t, 2H, J=7.5 Hz), 2.52 (br s, 8H), 2.36 (s, 3H), 2.19-2.29 (m, 2H), 1.39 (t, 3H, J=7.1 Hz).
