反応手順

Using the procedure outlined in Example 1 Step F, the title compound was prepared from 2-methoxy-ethylamine and 8-indan-5-yl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (Example 1, Step E, 10 mg, 0.022 mmol). 7 mg of 8-indan-5-yl-2-(2-methoxy-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): 9.25 (s, 1H), 8.47 (s, 1H), 7.35 (d, J=7.8 Hz, 1H), 7.22 (s, 1H), 7.14 (d, J=7.8 Hz, 1H), 5.99 (br, 2H), 4.37 (q, J=7.1 Hz, 2H), 3.45-3.35 (m, 2H), 3.29 (s, 3H), 3.00 (m, 4H), 2.18 (m, 2H), 1.38 (t, J=7.1 Hz, 3H).
