실험 절차

Phenyl 6-(2-fluoro-4-iodophenylamino)-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (compound 2A, 100 mg, 0.2 mmol, 1 eq) and O-(2-phenyl-1,3-dioxan-5-yl)hydroxylamine (79 mg, 0.404 mmol, 2 eq) (see, Vonhoff et al., Helv. Chim. Acta, 81(9), 1998; 1710-1725; European Patent Application No. EP1666485) were mixed in THF and subjected to microwave irradiation at 100° C. for 45 minutes. The reaction was complete by LCMS. Upon cooling, the intended product precipitated as a tan solid. 62 mg (51%). This solid was then dissolved in methanol (2 ml) and THF (2 ml) with ethylene glycol (100 μl). p-Toluenesulfonic acid (18 mg, 1 eq) was added and the mixture heated at 50° C. for 30 minutes. Purification by HPLC chromatography afforded the title compound as a white solid. 28 mg (53%). 1H NMR (400 MHz, DMSO-d6) δ ppm 2.96 (s, 3H) 3.22 (s, 3H) 3.42-3.58 (m, 4H) 4.00-4.08 (m, J=1.67, 0.78, 0.78, 0.78, 0.78 Hz, 2H) 4.75 (t, J=5.94 Hz, 2H) 5.76 (s, 1H) 7.53-7.62 (m, 1H) 7.80 (dd, J=9.73, 1.39 Hz, 1H) 11.99 (s, 1H) 12.23 (s, 1H) [M+H] calc'd for C16H18FIN4O6, 509; found, 509.
