Participants

Reaction Steps

Using the procedure outlined in Example 1(Step F) the title compound was prepared from 2-morpholin-4-yl-ethylamine (4.8 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). 15.5 mg of 8-indan-5-yl-2-(2-morpholin-4-yl-ethylamino)-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): 9.24 (s, 1H), 8.45 (s, 1H), 7.34 (d, 1H), 7.22 (s, 1H), 7.15 (d, 1H), 6.19 (br, 1H), 4.36 (q, 2H), 3.65 (m, 4H), 3.24 (m, 2H), 2.99 (m, 4H), 2.30-2.60 (m, 6H), 2.17 (m, 2H), 1.37 (t, 3H). Mass Spectrum (LCMS, ESI pos.) Calcd. For C25H29N5O4: 464.22 (M+H). Found: 464.4.
