2-Amino-6-Iodobenzothiazole

General procedure: A mixture of 0.1 mol of 4-substituted aniline and 0.1 mol of Potassium thiocyanate (KCNS) in 100 ml glacial acetic acid (AcOH) was cooled in an ice bath and stirred for 10-20 min, and then 0.1 mol bromine in glacial acetic acid was added dropwise at such a rate to keep the temperature below 10 °C throughout the addition. The reaction mixture was stirred at room temperature for 2-4 h, the hydrobromide (HBr) salt thus separated out was filtered, washed with acetic acid, dried, dissolved in hot water and basified to pH 11.0 with ammonia solution (NH(0143) Chloroform suspension (7 ml) of 1-(4-iodophenyl)thiourea (889 mg, 3.19 mmol) was added with bromine (328 μl, 6.40 mmol), and heated to reflux and stirred for 6 hours. After the reaction was completed and the solvent was removed, the residue was added with dichloromethane and washed with saturated sodium bicarbonate solution and saturated sodium chloride solution. After the solution was dried over anhydrous sodium sulfate and the solvent was removed under reduced pressure, the resulting deposits were filtered to obtain 650 mg 2-amino-6-iodobenzothiazole in a yield of 73percent.General procedure: A mixture of 0.1 mol of 4-substituted aniline and 0.1 mol of Potassium thiocyanate (KCNS) in 100 ml glacial acetic acid (AcOH) was cooled in an ice bath and stirred for 10-20 min, and then 0.1 mol bromine in glacial acetic acid was added dropwise at such a rate to keep the temperature below 10 °C throughout the addition.
