HBr in acetic acid (6 mL) was added to a suspension of benzo[b]thiophen-2-ylmethanol (1 g, 6.1 mmol) in dichloromethane (6 mL) at room temperature. The reaction mixture was stirred for 3 hours then diluted by addition of chloroform (20 mL). The organic phase was washed with a saturated solution of hydrogenocarbonate (20 mL), dried over sodium sulfate and concentrated to dryness. The title product was obtained as a yellow oil (1.3 g, quantitative).
