2-% (2,2-diethoxy) -N- (5,8-diethoxy [1,2,4] triazino [1,5-c] pyrimidine-2-yl) -6- (triethoxy) quinoxaline, this compound has the following physical properties:
Its appearance is often in solid form, with strong intermolecular forces and relatively regular molecular arrangements, forming a stable lattice structure. In terms of solubility, the compound has a certain solubility in common organic solvents such as ethanol and acetone. Because some of its structures have similar polarities or intermolecular forces to organic solvents, it can be dissolved through the interaction of van der Waals forces, hydrogen bonds, etc. with solvent molecules; but it has poor solubility in water. Because the overall hydrophobic groups of the molecule account for a large proportion, it is difficult to form effective interactions with water molecules.
Melting point is an important physical property parameter for the compound, and its melting point is in a specific temperature range, which depends on factors such as intermolecular forces and lattice energy. Chemical bonds between molecules and the spatial arrangement of substituents will affect the melting point. For example, the stronger the intermolecular hydrogen bonds and van der Waals forces, the greater the lattice energy and the higher the melting point. The boiling point is also affected by the intermolecular force and the relative molecular mass. The relative molecular mass is large and the intermolecular force is strong. The energy required for gasification is more, and the boiling point is correspondingly higher.
Density is also one of the characteristics of this compound. Its density value reflects the mass of the substance per unit volume, which is related to the packing tightness of the molecules and the relative molecular mass. In the solid state, the tightness of the molecules determines the density. If the intermolecular arrangement is compact and the number of molecules per unit volume is large, the density is relatively large.
In addition, the compound may have a certain refractive index. The refractive index is related to the structure of the molecule and the distribution of the electron cloud, which can reflect the refractive characteristics of light propagation in the substance, providing an important reference for the identification and analysis of the compound. These physical properties are crucial for understanding their behavior in chemical reactions, separation and purification, and practical applications.

To prepare 2- (2,2-diethoxyethyl) -N- (5,8-diethoxy [1,2,4] triazolo [1,5-c] pyrimidine-2-yl) -6- (triethoxy) quinazoline, the following ancient method can be carried out.
First take the appropriate raw material, take [1,2,4] triazolo [1,5-c] pyrimidine as the base, and introduce the ethoxy group at its 5,8 position. This step requires mild reaction conditions to ensure the selectivity of the reaction. Halogenated ethane and corresponding pyrimidine derivatives can be used in a basic environment with appropriate catalysts to make the ethoxy group connect smoothly.
Then, the two positions are modified to incorporate a group containing 2,2-diethoxyethyl group. This reaction can be carried out by means of nucleophilic substitution. The nucleophilic reagent containing diethoxyethyl group reacts with the pyrimidine derivative, during which the reaction temperature, time and reagent dosage need to be adjusted to obtain a high-purity product.
Furthermore, triethoxy is introduced into the quinazoline part. First, the skeleton of quinazoline can be constructed by cyclization of the corresponding aniline derivative and formamide and other reagents. Then, triethoxy is introduced at the 6th position. In this step, an electrophilic substitution reaction can be used to connect the triethoxy group to the 6-position quinazoline with a triethoxylation reagent under the action of a suitable Lewis acid catalyst.
After each step of the reaction, ancient purification methods such as recrystallization, column chromatography, etc. are required to remove impurities to obtain a pure product. Each step of the reaction requires fine operation and close monitoring to make this synthesis path proceed smoothly, and finally the product of 2- (2,2-diethoxyethyl) -N- (5,8-diethoxy [1,2,4] triazolo [1,5-c] pyrimidine-2-yl) -6- (triethoxy) quinazoline can be obtained.
