실험 절차

To a mixture of (S)-methyl 2-amino-3,3-dimethylbutanoate (200 mg, 1.377 mmol) and DIEA (0.481 mL, 2.75 mmol) in DCM (2 mL) solution was add 1-adamantyl fluoroformate (334 mg, 1.515 mmol). The reaction mixture was stirred at rt overnight. The compound was purified by silica gel column chromatography (20% EtOAc/80% hexane) to give a colorless oil (358 mg, 68%) as product.
