Procedure

4-Fluorobenzene-1,2-diamine (10.0 g, 0.077 mol) and potassium O-ethyl carbonodithioate (37.1 g, 0.234 mol) were dissolved in dry DMF (150 mL) under nitrogen and heated to 95° C. for 12 h. The reaction was cooled to RT and 200 mL water was added followed by addition of 5N HCl to get precipitates. After stirring for 1 h, the precipitates were collected by filtration, washed with water and dried under vacuum for 2 h. The crude compound was then washed with chloroform and dried to give 6-fluorobenzo[d]thiazole-2-thiol as yellow solid.
