Versuchsvorschrift

Thionyl chloride (0.415 mL, 5.69 mmol) was added slowly to an ice cold solution of the alcohol (510) (0.203 g, 1.14 mmol) in dichloromethane (6.0 mL). The reaction mixture was stirred and warmed to room temperature for 1 h. The resulting solution was quenched slowly with saturated sodium bicarbonate (10 mL) and extracted with dichloromethane, the organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to provide the intermediate 7-(chloromethyl)-2-methylbenzo[b]thiophene (511) (0.150 g, 67.0%) as a yellow oil.
