Due to the existence of various forces between molecules, such as van der Waals forces, hydrogen bonds, etc., the molecules are arranged in an orderly manner to form a crystalline structure.
In terms of melting point, such compounds containing polar groups such as nitrogen and cyanyl groups have strong intermolecular forces, so the melting point is relatively high. The specific value will vary due to factors such as purity and crystal structure, and is roughly in a certain temperature range, which is of great significance for its separation, purification and identification. The purity and authenticity of the substance can be preliminarily judged by melting point determination. < Br >
In terms of solubility, because its molecule contains polar cyanyl groups, it has relatively good solubility in polar solvents (such as water and alcohols), but poor solubility in non-polar solvents (such as alkanes). This property is conducive to its dissolution, extraction and reaction operations in different solvent systems. In organic synthesis, a suitable solvent can be selected according to the solubility characteristics to promote the smooth progress of the reaction or achieve product separation.
In terms of stability, the cyanyl and pyrimidine ring structures give it certain chemical stability, but under certain conditions (such as strong acid, strong base, high temperature and the presence of specific catalysts), cyanyl groups may undergo hydrolysis, addition and other reactions. Pyrimidine rings may also participate in some nucleophilic substitution, cyclization and other reactions. Pay attention to environmental conditions during storage and use to avoid unnecessary chemical reactions.
In appearance, pure 2-% (cyanomethyl) -5-cyanofurano [d] pyrimidine is usually white or off-white crystal, but if it contains impurities, the color and appearance may change. By observing the appearance color and morphology, its purity can be preliminarily judged.

2-% (cyanomethyl) -5-cyanofurano [d] pyrimidine, this property is particularly important and is related to the characteristics of many chemical changes.
Its shape is mostly crystalline and often appears in specific chemical synthesis scenarios. The melting point is quite critical.

The common synthesis methods of 2-% (methoxy) -5-bromopyridine [d] pyrimidine generally include the following:
First, the corresponding halogenated pyrimidine and pyrimidine derivatives are used as starting materials and achieved by the coupling reaction catalyzed by transition metals. In this process, transition metal catalysts such as palladium and nickel are often used with suitable ligands. Under specific reaction conditions, the halogenated atom of the halogenated pyrimidine is coupled to the active check point of the pyrimidine derivative, and then the core skeleton of the target product is constructed. For example, using 2-halo-5-bromopyridine and pyrimidine derivatives as substrates, heating the reaction in a suitable solvent in the presence of palladium catalyst and suitable ligands, and carefully adjusting the reaction temperature, time and proportion of reactants can effectively improve the yield and selectivity of the reaction.
Second, synthesize through the construction reaction of pyrimidine rings. First prepare pyrimidine derivatives with suitable substituents, and then use this as a basis to construct pyrimidine rings through multi-step reactions. For example, using pyrimidine containing specific substituents as the starting material and the precursor containing pyrimidine ring structure fragments, under acidic or basic conditions, cyclize to form the target product. This path requires precise control of the reaction conditions, flexible adjustment of the reaction reagents and conditions according to the electronic effects and steric resistance of different substituents, in order to achieve the desired reaction effect.
Third, the functional group conversion strategy is adopted. Compounds with similar structures are synthesized first, and then the functional groups are gradually converted to obtain 2- (methoxy) -5-bromopyridine [d] pyrimidine. For example, pyrimidine derivatives containing convertible functional groups are prepared first, and then the original functional groups are converted into methoxy and bromine atoms through substitution, oxidation, reduction, etc., so as to achieve the synthesis of the target product. This method has high requirements for the design of reaction steps and the selectivity of each step, and requires careful planning of reaction sequence and conditions to avoid side reactions.
During the synthesis process, factors such as solvent selection, reaction temperature, catalyst dosage, and reactant ratio all have a significant impact on the reaction process and the yield and purity of the product. Repeated experiments and optimization are required to find the best synthesis path.
