실험 절차
To a solution of 1-(2-methyl-1-propenyl)-3-nitrobenzene (4.57 g) in a mixture of methanol (50 ml) and 6N hydrochloric acid (14 ml) was added 10% palladium on activated carbon (1 g), and the mixture was stirred under hydrogen atmosphere (3 atm) at 25° C. for 3 hours. The catalyst was filtered off, and the filtrate was evaporated. The residue was poured into a mixture of ethyl acetate and aqueous sodium bicarbonate. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. Evaporation of the solvent gave 3-isobutylphenylamine (3.98 g) as a brown oil.
