실험 절차
A mixture of 10% palladium-carbon (50% wet, 50 mg) and 3-{[4-(1-methylethyl)phenyl]ethynyl}pyridin-2-amine (662.8 mg) in methanol (15 mL) was stirred under a hydrogen atmosphere at room temperature for 3 hr. The reaction mixture was filtered, a saturated aqueous sodium hydrogen carbonate solution was added to the filtrate, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (246.6 mg) as a colorless oil.
