White solid | [Uses]
5-Chloro-2-methylbenzothiazole undergoes an acid-catalyzed reaction with 3,4,5,6-tetrachloro-1,2-benzoquinone to give 5,6,7-trichloro-2-(5-chlorobenzothiazol-2-yl)-1,3-tropolone and 4,5,6,7-tetrachloro-2-(5-chlorobenzothiazol-2-yl)-1,3-tropolone[2]. 5-Chloro-2-methylbenzothiazole serves as a coupling partner to incorporate benzothiazole units into arylation products[3]. | [Synthesis]
5-Chloro-2-methylbenzothiazole is obtained in 41% yield as a white solid (mp 68–70 °C) by reacting aliphatic pyruvic acid with bis(2-aminophenyl) diselenide-type reagents[1]. | [References]
