実験手順

The resulting 1-[3,5-bis(trifluoromethyl)phenyl]ethyl azide (crude product: 111.5 mg) was dissolved in methanol (6 mL) and the solution was added with palladium-fibroin (18 mg) for hydrogen substitution, and then the mixture was stirred at room temperature for 1 hour. The reaction mixture was filtered through Celite, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (chloroform:methanol=50:1 to 5:1) to obtain 77.6 mg of 1-[3,5-bis(trifluoromethyl)phenyl]ethylamine as colorless oil (yield: 91%, for 2 steps).
