Participants

Reaction Steps

Using the procedure outlined in Example 1(g) the title compound was prepared from 3-dimethylaminoaniline dihydrochloride (7.6 mg, 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(e) above, 15 mg, 0.036 mmol) at the presence of triethylamine (11 μL, 0.072 mmol). 6.6 mg of 2-(3-dimethylamino-phenylamino)-8-indan-5-yl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester was obtained as a yellow solid. 1H NMR (300 MHz, CDCl3) δ (ppm): 9.41 (br, 1H), 8.53 (s, 1H), 7.47 (br, 1H), 7.40 (d, 1H), 7.29 (s, 1H), 7.18 (d, 1H), 6.90 (m, 2H), 6.50 (m, 2H), 4.39 (q, 2H), 3.00 (m, 4H), 2.80 (s, 6H), 2.21 (m, 2H), 1.37 (t, 3H). Mass Spectrum (LCMS, ESI pos.) Calcd. For C27H27N5O3: 470.21 (M+H), Found: 470.4.
