Participants

Reaction Steps

To a solution of N-Boc-N-methyl-L-alanine (200 mg), 2-aminobenzylamine (240 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (755 mg) and 1-hydroxybenzotriazole monohydrate (603 mg) in N,N-dimethylformamide (4 mL), N,N-diisopropylethylamine (355 μL) was added at room temperature, and the mixture was stirred at the same temperature for 9 hours. To the reaction mixture, water and ethyl acetate were added. The organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The organic layer and the extract were combined, washed successively with water and saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 75 to 50% hexane in ethyl acetate) to obtain oily (S)-tert-butyl (1-((2-aminobenzyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (C9, 47 mg).
