There are various methods for synthesizing 5-methyl-1H-pyrrolo [2,3-b] pyridine. The way to synthesize it often relies on the techniques of organic chemistry, through several steps of reaction to achieve the goal.
One method is to first take an appropriate starting material, which is based on the genus pyridine or pyrrole. Or choose a pyridine derivative with a specific substituent, and introduce the required group through the reaction of nucleophilic substitution to gradually build the structure of the target molecule.

Furthermore, the method of transition metal catalysis can be adopted. Transition metals such as palladium and nickel are used as catalysts to couple pyridine containing alkenyl and alkynyl groups with pyrrole derivatives. Transition metals can activate the chemical bonds of the substrate, reduce the energy barrier of the reaction, and make the reaction proceed under mild conditions. And this kind of catalytic reaction has high selectivity and can accurately construct the structure of the target molecule. The whole process of
synthesis requires attention to the control of the conditions of each step of the reaction, and the separation and purification of the product are also important.
