({4-[6-(4-hydroxy-3-methylphenyl)-2-oxo-2,3-dihydropyrimidin-4-yl]phenyl}oxy)-acetic acid (Compound 266, 17 mg, 48 umol) and 2-morpholinoethanamine (5.2 mg, 40 umol) were dissolved in dichloroethane (1.25 mL) and N,N-dimethylformamide (0.79 mL). To this solution was added 1-hydroxybenzotriazole (6.8 mg, 50 umol) followed by 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide methiodide (17.8 mg, 60 umol). The reaction mixture was stirred at room temperature for 15 hours and was concentrated in vacuo. The reaction mixture was purified by reverse phase HPLC to give 5 mg of product. 1H NMR (400 MHz, d6-DMSO): δ 8.23 (s, 1H), 8.14 (d, 2H), 8.03 (t, 1H), 7.94 (s, 1H), 7.85 (d, 1H), 7.33 (s, 1H), 7.09 (dd, 2H), 6.90 (d, 1H), 4.59 (s, 2H), 3.27-3.24 (m, 2H), 2.37-2.33 (m, 6H), 2.20 (s, 3H), 1.49-1.44 (m, 4H), 1.38-1.34 (m, 2H). MS (EI): 464 (MH+).
