Procedure

To a solution of NaOH (10N, 8.0 mL) was added 7-chloro-4-methyl-benzothiazol-2-ylamine (530 mg, 2.67 mmol) and ethylene glycol (10 mL) then the reaction mixture was stirred at 150° C. for 1 day. After being cooled down, the reaction mixture was filtered. The filtrate was extracted with DCM. The aqueous phase was acidified with HCl 1N and extracted with DCM. Then, the combined organic phases were washed with brine, dried over MgSO4, filtered and evaporated to yield 2-amino-6-chloro-3-methyl-benzenethiol (252 mg, 1.45 mmol, 54%) as a yellow oil.
