Procedure

8-Indan-5-yl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (105 mg, 0.25 mmol) and 3-dimethylaminomethyl-phenylamine (38 mg, 0.25 mmol) were combined in iPrOH (2 mL) and heated to 90° C. After 3 h, the reaction mixture was concentrated and purified by preparative HPLC (30 mL/min 5-100% MeCN/H2O gradient over 10 min) and lyophilized to provide 56 mg of 2-(3-Dimethylaminomethyl-phenylamino)-8-indan-5-yl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester. 1H NMR (400 MHz, CDCl3) δ (ppm): 9.31 (br s, 1H), 8.98 (br s, 1H), 8.51 (s, 1H), 8.39 (s, 1H), 7.00-7.53 (m, 7H), 4.28-4.40 (m, 2H), 3.64 (br s, 2H), 2.88-3.09 (m, 4H), 2.40 (s, 6H), 2.05-2.25 (m, 2H), 1.32-1.40 (m, 3H).
