methyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-2-carboxylate

Methyl 4-chloro-1H-pyrrolido [2,3-b] pyridine-2-carboxylic acid ester, which is an organic compound. Its physical properties are mostly solid at room temperature, with a certain melting point, which can vary according to specific conditions. In organic solvents, such as ethanol, acetone, etc., it has a certain solubility, but it has poor solubility in water. This is because the proportion of organic groups in its molecular structure is relatively large.
In terms of chemical properties, its ester group properties are active. In contact with water, hydrolysis reaction can occur under acid-base catalysis. In an acidic medium, 4-chloro-1H-pyrrolido [2,3-b] pyridine-2-carboxylic acid and methanol are hydrolyzed to form 4-chloro-1H-pyrrolido [2,3-b] pyridine-2-carboxylic acid; under alkaline conditions, hydrolysis is easier, and the products are corresponding carboxylic salts and methanol.
The pyridine ring and pyrrole ring parts have certain aromaticity due to the existence of a conjugated system, and electrophilic substitution reactions can occur. Chlorine atoms attached to the pyridine ring reduce the electron cloud density of the pyridine ring due to its electron-absorbing effect, and the electrophilic substitution reaction activity is lower than that of
In addition, the hydrogen on the nitrogen atom of the pyrrole ring has a certain acidity, and under the action of a strong base, it can be deprived of protons to generate corresponding nitrogen negative ions. As a nucleophilic reagent, this negative ion can react with many electrophilic reagents and expand the chemical transformation path of the compound.

The methods for preparing methyl 4-chloro-1H-pyrrolido [2,3-b] pyridine-2-carboxylic acid esters are many different, and this is the one described by you.
One method is to use suitable pyridine derivatives as starting materials. First, the pyridine ring is halogenated by a specific halogenation reaction to introduce chlorine atoms. This halogenation method, or chlorine gas, chlorination reagents, etc., under suitable reaction conditions, such as a specific temperature and solvent environment, the chlorine atom is precisely substituted in a specific position of the pyridine ring to obtain a chlorine-containing pyridine intermediate. Then, the pyrrole ring is constructed. In this step or by means of cyclization reaction, a suitable reagent is selected to cyclize the specific group in the molecule to form the skeleton structure of pyrrole [2,3-b] pyridine. Finally, through esterification reaction, the obtained pyrrole [2,3-b] pyridine derivative is reacted with methanol and suitable esterification reagents under catalytic conditions to obtain methyl 4-chloro-1H-pyrrole [2,3-b] pyridine-2-carboxylate.
There is another way to start with a compound containing pyrrole structure. First, the pyrrole ring is modified and a suitable substituent is introduced to prepare for the subsequent construction of the pyridine ring. Then, the pyridine ring is constructed through a series of reactions. During this process, attention is paid to the control of the reaction conditions to ensure the accuracy and selectivity of the pyridine ring construction. After the formation of pyrrolo [2,3-b] pyridine structure, chlorine atoms are introduced at suitable positions through chlorination reaction, and finally methyl 4-chloro-1H-pyrrolo [2,3-b] pyridine-2-carboxylic acid ester is prepared by esterification step. < Br >
