62266-82-4, 6-Bromobenzo[d]thiazol-2(3H)-one is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: One equivalent of appropriate heterocyclic derivative was dissolved in DMF. Three equivalents of potassium carbonate and 1.2 equivalent of the appropriate 3-chloropropan-1-amine derivative were added. The resulting mixture was heated at 70C until disappearance of the starting material. The reaction was monitored by TLC. After 24-96 h, the solvent was removed under reduced pressure, and water added to the residue. The crude product was extracted with dichloromethane. The combined organic fractions were washed with water and dried over magnesium sulphate. Purification by thick layer chromatography or column chromatography was performed.

62266-82-4, Example 12A 2-amino-5-bromothiophenol and its disulfide A mixture of 6-bromobenzothiazolone (CAS number 62266-82-4, Aldrich Chemical Company (12.9 g, 56.1 mmol), NaOH (33 g, 0.825 mol) and water (90 mL) was heated to 100 C. for 15 hours under nitrogen. The mixture was cooled to 0 C. and pH was adjusted to pH 5 using 5N acetic acid at 0-10 C. under nitrogen. The precipitate was filtered, washed with water and vac. dried at 45 C. to give the product as a mixture of 2-amino-5-bromothiophenol and its disulfide (11.47 g, 100%).
