Procedure
3,8-dimethyl-4,7-dioxo-3,4,7,8-tetrahydropyrido[2,3-d]pyrimidin-5-yl 4-methylbenzenesulfonate (compound 1D, 80 mg of 60% pure material) and 2-fluoro-4-iodoaniline (300 mg, large excess) were heated at 125° C. for 2 hours to yield 5-(2-fluoro-4-iodophenylamino)-3,8-dimethylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione (Example 1). The product was confirmed by LC-MS and isolated by HPLC to give the title compound as a tan solid (17 mg). 1H NMR (400 MHz, MeOD) δ ppm 3.57 (s, 3H) 3.64 (s, 3H) 5.76 (s, 1H) 7.30 (t, J=8.34 Hz, 1H) 7.61 (dt, J=8.34, 1.01 Hz, 1H) 7.66 (dd, J=9.85, 1.77 Hz, 1H) 8.48 (s, 1H); [M+H] calc'd for C15H12FIN4O2, 427; found, 427.
