white to light yellow crystal powder | [Uses]
Methyl 3-amino-2-thiophenecarboxylate was used in:
- the synthesis of 4-nitro and 4-aminothienyl ureas
- total synthesis of quinazolinocarboline alkaloids
- preparation of thienopyrimidinone analogs
| [General Description]
Methyl 3-amino-2-thiophenecarboxylate reacts with hydrazonoyl chlorides in the presence of triethylamine to yield corresponding N-arylamidrazones. |
