Participants

Reaction Steps

Commercially available (S)-2-BOC-amino-succinic acid 1-methyl ester (2.4 g, 10 mmol) was dissolved in DCM (30 mL), and triethylamine (2.8 mL, 20 mmol) was added thereto. To the mixture were added isopropanol (660 mg, 11 mmol), EDC (2.5 g, 26 mmol) and HOBt (2.3 g, 30 mmol), and the mixture was stirred for 4 h at room temperature. The reaction was quenched by saturated aqueous NaHCO3 solution. The reaction mixture was extracted with EtOAc, washed with saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography to give the title compound (2.5 g, Yield 87%).
