실험 절차

To a suspension of 4-amino-1-benzenesulfonyl-5-fluoro-1H-pyrimidin-2-one (0.20 g, 0.74 mmol) in anhydrous tetrahydrofuran (THF; 3 mL) was added sodium hydride (NaH; 0.044 g of 60 wt % suspension in mineral oil, 1.11 mmol) at 0° C. After gas evolution had subsided, the mixture was transferred via cannula to an ice-cold mixture of phenyl isothiocyanate (1.0 g, 7.4 mmol) in anhydrous THF (5 mL) and stirred for 6 h. The reaction mixture was diluted with EtOAc (25 mL), and the resulting solution was washed with satd aq ammonium chloride (NH4Cl; 15 mL) and brine (15 mL). The organic phase was dried over Na2SO4, filtered, and the solvent evaporated. The residue was purified by precipitation from methanol (MeOH) and Et2O to give (1-benzenesulfonyl-5-fluoro-2-oxo-1,2-dihydropyrimidin-4-yl)-3-phenylthiourea as a light yellow solid (0.025 g, 8%): mp 205-208° C.; 1H NMR (400 MHz, DMSO-d6) δ 11.26 (dd, J=3.7, 1.1 Hz, 1H), 10.87 (m, 1H), 8.65 (m, 1H), 8.10 (d, J=7.5 Hz, 2H), 7.85 (t, J=7.5 Hz, 1H), 7.71 (m, 2H), 7.45 (m, 2H), 7.34 (m, 2H), 7.10 (m, 1H); ESIMS m/z 405 ([M+H]+).
