Participants

Reaction Steps

4-bromo-2-cycloheptylidenemethylanisole (738 mg, 2.5 mmol) in THF (20 ml) was cooled to -78° C. while stirring under nitrogen. n-Butyllithium (1 ml, 2.5M in Hexane, 2.5 mmol) was added dropwise over 1 minute. N,N-Dimethylformamide (0.5 ml) was added rapidly. The ice bath was removed an the reaction was warmed to room temperature. The reaction was diluted with ethyl acetate (100 ml) and was washed with water (50 ml) and brine (50 ml). The organic solution was dried over MgSO4, filtered and concentrated. The product was purified via flash chromatography to yield 440 mg (1.8 mmol) of the title compound (72%).
