Reaction Steps
2 ml (2.00 mmol) of a 1 M potassium t-butoxide solution in tetrahydrofuran were added to a solution of 200 mg (2.02 mmol) of succinimide in 10 ml of dimethylformamide, and the resulting mixture was stirred at room temperature for 15 minutes. A solution of 680 mg (1.35 mmol) of N-[2-t-butyl-5-bromomethylphenyl]-3-(2,3-ethylenedioxyphenyl)octanamide (prepared as described in Preparation 70E) in 5 ml of dimethylformamide was then added to the mixture. The mixture was stirred at room temperature for 1 hour, after which water was added, and the aqueous mixture was extracted with diethyl ether. The extract was washed with 10% v/v aqueous hydrochloric acid, with a saturated aqueous solution of sodium hydrogencarbonate and a with saturated aqueous solution of sodium chloride, in that order, after which it was dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, and the resulting residue was purified by column chromatography through silica gel using a 2:3 by volume mixture of hexane and ethyl acetate as the eluent, to give 565 mg of the title compound as a colorless foam-like substance in a 80% yield.
