This process needs to prevent hydrolysis of acid chloride, the solvent needs to be anhydrous, and the tail gas contains hydrogen chloride, which needs to be properly handled.
Second, use suitable halogenated compounds as raw materials, such as 4,5,6,7-tetrahydro-1-benzothiophene-3-halogenated compounds, react with cyanides such as sodium cyanide or potassium cyanide to form nitrile intermediates. Nitriles can be hydrolyzed to carboxylic acids under acid or base catalysis, and then react with ammonia or amine to form amides. In this step, attention should be paid to the toxicity of cyanide. The operation should be cautious, and protection and waste treatment should be done.
Third, alkenone compounds containing benzothiophene structure are reacted with ammonia or amine. Enones are electrophilic and can be added to nucleophilic ammonia or amines. After rearrangement, the target amide is obtained. The conditions of this process are mild, but the preparation of ketenes may be more complicated, and multi-step reactions are required. The selection of raw materials and the control of reaction conditions are crucial.
The above methods have their own advantages and disadvantages. The actual synthesis requires multiple factors such as raw material availability, cost, reaction conditions and product purity to weigh and choose the optimal path.
