White to yellow solid | [Synthesis]
Using benzothiophene as starting material in dichloromethane (DCM) solvent, potassium acetate was added as a base, followed by bromination reaction with dropwise addition of bromine to give 2,3-dibromothiophene (compound 12) as a white solid in 100% yield. In addition, the target compound X can be synthesized by replacing compound (11) in formula (1). | [References]
