실험 절차
A mixture of intermediate 24 (272 mg, 1.65 mmol) and hydroiodic acid (45%, 2 mL) was heated to reflux for 5 h. The mixture was diluted with water and filtered. The filtrate was neutralized and the solids were filtered, washed with water, and combined to give benzo[d]thiazol-5-ol (intermediate 25) (206 mg, 83%). HPLC: 99%, RT 2.038 min. MS (ESI) m/z 152.1 [M+H]+.
