To a mixture of 3-(2,4-dinitrophenyl)-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione 24A (18 mg, 0.03 mmol, 1 eq) in DMF (0.3 mL) was added 2-aminopropane-1,3-diol (29 mg, 0.3 mmol, 10 eq). The reaction mixture was heated at 80° C. for 5 hours. The solvent was removed under vacuum and the residue was purified by preparatory LC/MS (30-55% CH3CN in H2O) to yield 3-(1,3-dihydroxypropan-2-yl)-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione Example 24 as an off-white solid (10 mg, 66% yield). 1H NMR (400 MHz, MeOD) δ ppm 3.65 (s, 3 H) 3.87-3.95 (m, 2 H) 4.04 (dd, J=11.87, 7.07 Hz, 2 H) 4.88-4.90 (m, 1 H) 5.74 (s, 1 H) 7.29 (t, J=8.34 Hz, 1 H) 7.57-7.69 (m, 2 H) 8.50 (s, 1 H). [M+H] calc'd for C17H16FIN4O4, 487; found, 487.
