실험 절차

Sodium hydride (67 mg, 3.5 mmol, 5 eq) was stirred in anhydrous DMF (500 μL) for 10 minutes. 5-(2-fluoro-4-iodophenylamino)-6,8-dimethylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione (300 mg, 0.70 mmol, 1 eq, Example 12) in anhydrous DMF (300 μL) was added and the mixture stirred for 10 minutes. (R)-4-(Chloromethyl)-2,2-dimethyl-1,3-dioxolane (180 μL, 1.32 mmol, 5 eq) was added and the mixture subjected to microwave irradiation at 135° C. for 1 hour. The solvent was removed in vacuo. The residue was taken up in H2O (1 mL) and THF (1 mL). 1N HCl (1 mL) was added and the solution stirred at RT for 1 hour. After evaporation in vacuo the residue was purified by HPLC to give 88 mg (25%) of the title compound. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.64 (s, 3H) 2.11 (s, 3H) 3.18 (d, J=5.31 Hz, 1H) 3.32-3.42 (m, 1H) 3.63-3.70 (m, 1H) 3.70-3.82 (m, 1H) 4.24-4.38 (m, 1H) 4.78 (t, J=5.56 Hz, 1H) 5.09 (d, J=5.56 Hz, 1H) 6.62 (t, J=8.72 Hz, 1H) 7.45 (dd, J=7.71, 2.15 Hz, 1H) 7.66 (dd, J=10.61, 2.02 Hz, 1H) 8.48 (s, 1H) 10.16 (s, 1H) [M+H] calc'd for C18H18FIN4O4, 501. found, 501.
