Process for the synthesis of 5-amino tetrazole derivatives |
| abstract |
An improved process for the preparation of 3-chlorobenzo[b]thiophene-2-carbonyl chlorides is described where a cinnamic acid is converted in the presence of thionyl chloride and a 4-N,N'-disubstituted aminopyridine in one step to the desired product. |
