Abstract:
The synthesis of 6-hydroxybenzothiazole-2-carboxylic acid (1) is presented. The benzothiazole ring was obtained by ring contraction of a remarkably stable 2-alkoxy-7-hydroxy-2H-benzo [1,4]thiazine intermediate that could be isolated. 6-Hydroxybenzothiazole 2-carboxylic acid was found to slowly decarboxylate in solution at ambient temperature.
