Using the procedure outlined in Example 1(Step F) the title compound was prepared from N1,N1-dimethyl-propane-1,3-diamine (4.6 μL, 0.036 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(Step E), 15 mg, 0.036 mmol). 9.7 mg of 2-(3-dimethylamino-propylamino)-8-indan-5-yl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester was obtained as a white solid. 1H NMR (400 MHz, CDCl3) δ (ppm): 9.23 (s, 1H), 8.46 (s, 1H), 7.34 (d, 1H), 7.23 (s, 1H), 7.13 (d, 1H), 6.77 (br, 1H), (m, 2H), 2.99 (m, 4H), 2.19 (m, 10H), 1.60 (m, 2H), 1.37 (t, 3H). Mass Spectrum (LCMS, ESI pos.) Calcd. For C24H29N5O3: 436.23 (M+H). Found: 436.4.
