実験手順
To an ice-cold solution of 3-methylbenzothiophene-2-methanol [Reference example 1] (480 mg, 2.69 mmol) in benzene (10 mL) was added dropwise, a solution of thionyl chloride (0.24 mL, 3.2 mmol) in benzene (3.5 mL). The mixture was stirred at room temperature for 3 hour, and concentrated under reduced pressure to give 2-chloromethyl-3-methylbenzothiophene as a yellow oil (548 mg, yield>99%).
