実験手順

To a 7 milliliter (mL) screw-cap vial were added dichloromethane (CH2Cl2; 5 milliliters (mL)), N′-(5-fluoro-2-hydroxy-pyrimidin-4-yl)-N,N-dimethylformamidine (200 milligrams (mg), 1.09 millimoles (mmol)), and propyl isocyanate (94 mg, 1.10 mmol). The mixture was shaken at room temperature for 16 hours (h). After evaporation and recrystallization of the crude product from CH2Cl2 and heptane, the title compound was isolated as a white solid (274 mg, 94%): mp 266-268° C.; 1H NMR (300 MHz, CDCl3) δ10.42 (br s, 1H), 8.84 (s, 1H), 8.46 (d, J=6.6 Hz, 1H), 3.39-3.30 (m, 2H), 3.25 (s, 6H), 1.70-1.57 (m, 2H), 0.97 (t, J=7.4 Hz, 3H); ESIMS m/z 270 ([M+H]+).
