Examples
Embodiment 1
[0057] Embodiment 1. compound general synthetic method
[0058] Dissolve uracil derivative (10mmol) and 4-dimethylaminopyridine (0.5mmol) in pyridine (20mL), heat up to 60°C, slowly add isocyanate (20mmol) dropwise, and react at this temperature for 5h. Pyridine was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography to obtain the product.
Embodiment 2
