Reaction Steps
To a solution of 5-bromo-2-fluorobenzenamine (200 mg, 1.28 mmol) in N-methyl-2-pyrrolidine (1.5 mL) was added potassium o-ethyl carbonodithioate (410 mg, 2.56 mmol). The mixture was heated at 140° C. for 2 h. The reaction mixture was poured into a large amount of water, acidified with concentrated hydrochloric acid, and filtered to give 5-bromo-benzothiazole-2-thiol 300 mg (95%).
