실험 절차

To a solution of 6-fluoro-5-methoxy-1,1-dimethyl-indan (1.40 g, 7.21 mmol) in 20.0 ml of DCM at −78° C. was added BBr3 (1.40 ml, 14.4 mmol) in DCM (10.0 ml). The reaction mixture was stirred at −78° C. for two hours before being treated with 2.0 ml of methanol. This mixture was stirred for few minutes after which a saturated solution of NaHCO3 was carefully added and the resulting mixture stirred for an additional 1 hour. The mixture was extracted with DCM (3×40 mL) and the combined organic extracts were washed with brine and dried over Na2SO4. Flash column chromatography on silica gel (2-10% ethyl acetate/heptanes) afforded 0.985 g of the title compound.
