Participants

Reaction Steps

Using the procedure outlined in Example 1 Step F, the title compound was prepared 2-(4-methoxyphenyl)-ethylamine 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, 20 mg, 0.04 mmol). 19 mg of 8-Indan-5-yl-2-[2-(4-methoxy-phenyl)-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): 9.23 (s, 1H), 8.47 (s, 1H), 7.37 (d, J=7.8 Hz, 1H), 7.26 (s, 1H), 7.18 (d, J=7.8 Hz, 1H), 6.81 (d, J=8.6 Hz, 2H), 6.77 (d, J=8.6 Hz, 2H), 5.84 (br, 1H), 4.37 (q, J=7.1 Hz, 2H), 3.78 (s, 3H), 3.34 (m, 2H), 3.00 (m, 7H), 2.64 (t, J=7.2 Hz, 2H), 2.18 (m, 2H), 1.38 (t, J=7.1 Hz, 3H).
