실험 절차

301 mg (4.60 mmol) of zinc dust and then 5 ml of 2N aqueous hydrochloric acid were added to a solution of 430 mg (0.92 mmol) of N-(2-t-butyl-5-azidomethylphenyl)-3-(2,4-dimethoxyphenyl)octanamide [prepared as described in step (i) above] in 10 ml of acetone, and the resulting mixture was stirred for 1 hour. At the end of this time, the reaction mixture was filtered to remove zinc dust, and the filtrate was made alkaline by adding a saturated aqueous solution of sodium hydrogencarbonate. The mixture was then extracted with ethyl acetate. The extract was washed with water and then with a saturated aqueous solution of sodium chloride, after which it was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and the resulting residue was purified by column chromatography through 50 g of silica gel using a 10:1 by volume mixture of ethyl acetate and methanol as the eluent, to give 354 mg (yield 86%) of the title compound as a foam-like substance.
