Reaction Steps

Pd2(dba)3 (267 mg, 0.29 mmol), BINAP (363 mg, 0.58 mmol), sodium tert-butoxide (841 mg, 8.75 mmol) and benzophenone imine (1.05 g, 0.98 mL, 5.83 mmol) were added to a solution of the crude 5-bromo-7-fluoro-1,1-dimethylindane in anhydrous toluene (30 mL) at room temperature, and the mixture was stirred at 80° C. for 1 hr under argon atmosphere. To the reaction mixture was added ice water, and the mixture was extracted with ethyl acetate (×2). The organic layer was concentrated under reduced pressure to give crude N-(7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)-1,1-diphenylmethanimine as an orange oil.
