실험 절차
To an ice-cold, stirred suspension of sodium hydride (2.59 g, 64.8 mmol) in toluene (90 mL) was added dropwise a solution of (S)-2-amino-3-methylbutan-1-ol (3 g, 29.1 mmol) in toluene (60 mL). The reaction was then warmed to room temperature and a solution of ethyl chloroacetate (3.56 g, 29.1 mmol) in toluene (16 mL) was added dropwise. The resulting mixture was heated to reflux for 20 h under nitrogen and then concentrated under vacuum. The residue was purified by flash chromatography to afford 2.8 g of product (MS: (M+H)=144.3).
