The reaction of cinnamic acid derivatives with thionyl chloride and pyridine is a general procedure for the preparation of derivatives of 3‐chlorobenzo[ b ] thiophene‐2‐carbonyl chloride from readily accessible starting materials. These compounds are easily converted to the corresponding acids, esters and amines.
