실험 절차

To a solution of (5-bromo-2,2-dimethyl-2,3-dihydrobenzofuran-7-yl)methanol (669) (390 mg, 1.51 mmol) in dichloromethane (15 mL) was added thionyl chloride (0.56 mL, 7.58 mmol). The reaction was stirred at room temperature for 2 hours and then concentrated to afford 5-bromo-7-(chloromethyl)-2,2-dimethyl-2,3-dihydrobenzofuran (670).
