3 - methyl - benzo [b] thiophene - 2 - carbonitrile, that is, 3 - methyl - benzo [b] thiophene - 2 - formonitrile, its synthesis method is common as follows:
First, it can be 3 - methylbenzo [b] thiophene starting. First, 3-methylbenzo [b] thiophene is halogenated to introduce halogen atoms at suitable positions, such as bromine atoms at the 2-position. The reagent used can be N-bromosuccinimide (NBS). In the presence of an initiator such as benzoyl peroxide (BPO) and under lighting conditions, a free radical substitution reaction occurs to generate 2-bromo-3-methylbenzo [b] thiophene. Then, the bromide product and cuprous cyanide (CuCN) are heated and refluxed in a high-boiling polar solvent such as N, N-dimethylformamide (DMF), and the bromine atom is replaced by a cyanyl group to obtain 3-methyl-benzo [b] thiophene-2-formonitrile. In this process, the halogenation step needs to pay attention to the mild control of the reaction conditions to avoid the generation of polyhalogenated by-products; the cyanyl substitution step should ensure the purity of the reagent and the reaction system is anhydrous, because water will decompose cuprous cyanide, which will affect the reaction progress.
Second, a suitable thiophene derivative is used as the starting material to construct a benzothiophene ring. For example, using 2-methyl-3- (2-bromophenyl) thiophene as a raw material, in the presence of palladium catalysts such as tetrakis (triphenylphosphine) palladium (Pd (PPh)) and bases such as potassium carbonate (K ² CO ²), cyanylation occurs with zinc cyanide (Zn (CN) ²), and during the reaction, the benzo [b] thiophene ring is constructed by means of an intramolecular ring-closing reaction, and the final product is 3-methyl-benzo [b] thiophene-2-formonitrile. This route requires precise control of catalyst dosage and reaction temperature. Palladium catalysts are expensive, and excessive dosage increases costs and may lead to side reactions. Improper temperature will affect the balance and rate of cyclization and cyanylation reactions.
