Two representative compounds have been determined by X-ray crystallography. The best ratio of reactants, the adequate reaction temperature and solvent have been found by contrast experiments.4. The better photoreaction conditions and irridation times have been confirmed through the different photoreaction results. It is the first time that fifty quinazoline derivatives with biological activity and four photooxidation products with urea functional groups have been obtained by photochemistry method. Two representative compounds, quinazoline derivatives and photooxidation products, have been determined by X-ray crystallography, respectively.
