Description

2-Chlorobenzothiazole was used in the synthesis of:(RS)- and (S)-lubeluzole(1,3-benzothiazol-2-yl) amino-9-(10H)-acridinone derivatives4H-thieno[2,3:4,5]pyrimido[2,1-b]benzothiazole derivatives

Application

2-Chlorobenzothiazole serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted benzothiazoles via palladium-catalyzed cross-coupling reactions. Its electrophilic chlorine atom facilitates nucleophilic substitution under mild conditions, offering reliable functionalization for pharmaceutical and agrochemical scaffolds. The compound exhibits excellent bench stability and compatibility with common protecting groups, simplifying purification and scale-up in synthetic workflows.
