"5 - [[[( 2,4 -divinylphenyl) methyl] urea] guanidine]" part, 2,4 -divinylphenyl indicates that the 2 and 4 positions of the styrene ring are connected with vinyl, which is then connected to methyl, and then connected to urea and guanidine in turn.
"1 - (2,2 -dimethoxyethyl) ", that is, the first position of the main chain is connected with 2,2 -dimethoxyethyl.
"1,4-diazo-4-oxo-3- (benzoxy) " means that the main chain contains two nitrogen atoms, one of which is at the 4-position and is connected to the oxygen atom to form a carbonyl group, and the 3-position is connected with a benzoxy group.
"2-to-its carboxyl formamide", indicating that the 2-position is connected to the carboxyl formamide.
In summary, this compound has a complex structure and is formed by connecting multi-part groups in a specific order. Each group affects each other to jointly determine its chemical properties and spatial configuration.

I have just heard that your inquiry is about the physical properties of (2,4-divinylphenyl) methylaminoguanidine-1- (2,2-dimethoxyethyl) -1,4-dinitrogen-4-oxo-3- (phenylmethoxy) -2-to its carboxybenzoic acid compounds. These compounds have complex structures and unique properties.
First, its solubility is mentioned. Because its molecule contains polar carboxyl groups, oxygen groups and other groups, it may have a certain solubility in polar solvents such as water. However, non-polar parts such as benzene rings also limit their solubility. In general, the solubility in water may not be high, while in organic solvents such as alcohols, the solubility may be slightly better.
Let's talk about the melting point and boiling point. In view of the interaction of hydrogen bonds, van der Waals forces, etc. between the molecules, and the relatively rigid structure, its melting point, boiling point or higher. The atoms in the molecule are connected by covalent bonds to form a stable structure. To melt or boil it, more energy needs to be provided to overcome the intermolecular force.
In terms of density, because it contains a variety of atoms and has a compact structure, the density may be greater than that of common hydrocarbons. And its refractive index, due to the distribution of electron clouds and chemical bond characteristics within the molecule, or presents a specific value, reflects its influence on light propagation.
In addition, the polarity of the compound is determined by its functional group, and the polarity is strong, which also affects its behavior in the electric field. And because it contains heteroatoms such as nitrogen and oxygen, or has a certain dipole moment, it affects the interaction between molecules and the reactivity with other substances.

To prepare 5 - [[[（ 2,4 - divinylphenyl) methyl] amino] benzyl] - 1 - (2,2 - dimethoxyethyl) - 1,4 - dihydro - 4 - oxo - 3 - (benzyl methoxy) - 2 - benzyl pyridinecarboxylate, the synthesis method is as follows:
The starting material needs to be carefully selected, which involves benzene, pyridine and other compounds containing specific substituents. First, for the construction of (2,4-divinylphenyl) methyl-related structures, the nucleophilic substitution or addition reaction of 2,4-divinylphenyl groups to methyl groups can be carried out with benzyl derivatives under suitable reaction conditions by suitable vinylation reagents under suitable reaction conditions, such as in an inert gas protective atmosphere, catalyzed by a specific metal catalyst.
For the 2,2-dimethoxyethyl group part, dimethoxyethyl groups can be introduced by nucleophilic substitution reaction with dimethyloxy compounds under basic conditions starting from the corresponding halogenated ethane derivatives.
The formation of 1,4-dihydro-4-oxo-3- (phenylmethoxy) -2-benzyl pyridinate structures on the pyridine ring requires a multi-step reaction. The parent nucleus of the pyridine ring is first constructed, and the ring is closed by a suitable nitrogen-containing and carbonyl-containing compound under the action of a condensation reagent, and then the pyridine ring is modified by oxidation, etherification, and esterification. For example, the specific position on the pyridine ring is oxidized to a carbonyl group by a suitable oxidant, and then the benzyl methoxylation reagent is introduced into the benzyl group, and finally the benzyl pyridinate structure is formed with benzyl alcohol under esterification conditions.
In each step of the reaction process, the reaction temperature, reaction time and the proportion of the reactants should be strictly controlled, and the separation and purification of the intermediates should be paid attention to. Column chromatography, recrystallization and other means can be used. Finally, through multi-step reaction and post-treatment, the target product 5 - [[[（ 2,4-divinylphenyl) methyl] amino] benzyl] -1 - (2,2-dimethoxyethyl) -1,4-dihydro-4-oxo-3 - (benzyl benzyl) -2-pyridinecarboxylate can be obtained.
