The synthesis method of 1H-pyrrole-3-formonitrile, 2-amino-4,5-dimethyl-1 - (phenylmethyl) is involved in the field of organic synthesis. There are many methods, which are briefly described below.
First, a compound containing a pyrrole structure is used as the starting material. A suitable pyrrole derivative can be taken first and modified at a specific position. For example, starting with 2-methyl-4-nitropyrrole, the nitro group is converted into an amino group through a reduction reaction. Commonly used reducing agents such as iron-hydrochloric acid system or hydrogen-palladium carbon catalyst can obtain 2-methyl-4-amino pyrrole. Subsequently, cyano is introduced at the 3-position of pyrrole, and this step can be achieved by means of a nucleophilic substitution reaction, using halogenated cyanide as a reagent and catalyzed by an appropriate base. Furthermore, the 1-position is alkylated, and halobenzyl is used as an alkylating agent. In the presence of a base, 1- (phenylmethyl) -2-methyl-4-amino-3-cyanopyrrole can be formed. After that, the 5-position is methylated, and methylating reagents such as iodomethane can be selected. Under alkali catalysis, the synthesis of 2-amino-4,5-dimethyl-1- (phenylmethyl) -1H-pyrrole-3-formonitrile can be completed.
Second, the strategy of constructing pyrrole rings can also be adopted. Using 1,4-dicarbonyl compound and ammonia or amine as raw materials, under acidic or basic catalysis, the pyrrole ring is constructed by Paal-Knorr reaction. For example, with 2,5-hexanedione and aniline as starting materials, under the catalysis of p-toluenesulfonic acid, 2-methyl-4-phenylpyrrole is formed. Subsequently, amino, cyano and methyl groups are introduced into the pyrrole ring at specific positions in a similar manner as described above to achieve the synthesis of the target product. Precise control of each reaction condition, such as temperature, reaction time and reagent dosage, is required to obtain a product with good yield and purity.

1H-pyrrole-3-formonitrile, 2-amino-4,5-dimethyl-1- (phenylmethyl), has unique characteristics in chemical reactions.
The structure of this compound is specific, and its pyrrole ring is connected to cyano, amino, dimethyl and benzyl, which gives it unique reactivity. Pyrrole ring has electron-rich properties, which is easy to attract electrophilic reagents to attack, resulting in electrophilic substitution reactions on the ring, such as halogenation, nitration, sulfonation, etc. The amino group is a strong electron donor group, which can strengthen the electron cloud density of the pyrrole ring and make the electrophilic substitution easier. The amino group can participate in many reactions, such as salting with acids and condensing with aldones and ketones to form Schiff bases. Cyanyl is chemically active and can be hydrolyzed to carboxyl groups, or reduced to amino groups, expanding the reaction path.
The effect of steric resistance cannot be ignored. The presence of methyl and benzyl groups in the molecule increases the steric resistance. This has a great impact on the selectivity of the reaction. When the electrophilic reagent attacks, it tends to have a check point with small steric resistance. For example, electrophilic substitution, the reagent is more likely to attack the unsubstituted pyrrole ring and the space is open.
Furthermore, the aromaticity of this compound also affects the reaction The pyrrole ring conforms to the Hocker rule and has a certain aromaticity, which makes it relatively stable. When participating in the reaction, it will maintain the aromatic structure. For example, in the electrophilic substitution, the aromatic system is still retained after the reaction to maintain stability.
In terms of solubility, due to the presence of polar groups such as amino and cyano, as well as non-polar benzyl and methyl, it has certain solubility in both polar and non-polar solvents. The reaction rate and equilibrium can be adjusted according to the reaction demand.
