Reaction Steps
To a solution of 6-bromo-5-methoxy-1,1-dimethyl-indan (2.77 g, 10.8 mmol) (see Example 5) in THF (40 mL) at −78° C. was slowly added n-butyllithium (5.56 ml, 2.5M). The resulting solution was stirred at −78° C. for 0.5 h and a solution of N-fluorobenzenesulfonimide (4.11 g, 13.0 mmol) in THF (40 mL) was added. After an additional 2 h at −78° C., the reaction was warmed to room temperature, poured into water (50 mL), and extracted with ethyl acetate (2×80 mL). The combined organic layers were washed with water (100 mL), dried over sodium sulfate, filtered, and concentrated. Silica gel chromatography (2% ethyl acetate/heptanes) afforded 1.40 g of the title compound as yellow oil.
