Reaction Conditions

Reaction Steps

L-alanine methyl ester hydrochloride (15.0 g, 107 mmol) was dissolved in N,N′-dimethylformamide (150 mL), added potassium carbonate (32.5 g, 235 mmol) and benzyl bromide (18.4 g, 107 mmol) and the mixture was stirred at 80° C. overnight. Then, the mixture was reverted to room temperature, the reaction solution was filtered through a pad of celite, extracted with ethyl acetate, washed with water and brine, dried over sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and the title compound (12.7 g, 61%) was obtained as a colorless oil.
