実験手順
Methyl (S)-2-t-butoxycarbonylamino-6-methyl-6-nitroheptanoate (300 mg, 0.94 mmol) was dissolved in methanol (10 ml) and 5% palladium-carbon (0.15 g, 50% wet) was added. The mixture was stirred at a hydrogen pressure of 20 atm and 80° C. for 24 h. Palladium-carbon was removed by filtration and methanol was evaporated by concentration under reduced pressure to give the objective compound (219 mg, yield 80.8%).
