실험 절차

To a solution of 3-amino-3-(3-bromo-phenyl)-propionic acid (1.0 g, 4.1 mmol) in methanol-toluene (100 mL; 1:1 solution) at room temperature is added trimethylsilyl diazomethane (2.0 M solution in hexanes, 20 mL, 40 mmol). After 30 min, excess trimethylsilyl diazomethane is quenched by addition of glacial acetic acid (5 mL). Concentration in vacuo affords of 3-amino-3-(3-bromo-phenyl)-propionic acid methyl ester (1.0 g, 95%) as a colorless liquid which solidifies upon standing.
