実験手順

To a mixture of 5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione 5F (41 mg, 0.1 mmol, 1 eq) and catalytic amount of potassium iodide in DMF (1 mL) was added potassium carbonate (21 mg, 0.15 mmol, 1.5 eq). The reaction mixture was stirred at ambient temperature for 5 minutes. 1-Chloro-2,4-dinitrobenzene (22 mg, 0.11 mmol, 1.1 eq) was then added and the reaction mixture was irradiated with microwave at 80° C. for 30 minutes and then at 100° C. for 30 minutes. The reaction mixture was filtered and the filtrate was purified by preparatory LC/MS (50-75% CH3CN in H2O) to give 3-(2,4-dinitrophenyl)-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione compound 24A as a yellow solid (18 mg, 31% yield). 1H NMR (400 MHz, CDCl3) δ ppm 3.78 (s, 3 H) 6.09 (s, 1 H) 7.17-7.24 (m, 1 H) 7.52 (d, J=8.34 Hz, 2 H) 7.72-7.80 (m, 1 H) 8.23 (s, 1 H) 8.75 (dd, J=8.46, 2.65 Hz, 1 H) 9.12 (d, J=2.53 Hz, 1 H) 9.83 (s, 1 H). [M+H] calc'd for C20H12FIN6O6, 579; found, 579.
