실험 절차

To a stirred solution of (S)-phenylglycine (50 g, 0.3 mol) in MeOH (500 mL) at 0° C. was added thionyl chloride (42.84 g, 0.36 mol) dropwise. After stirring for 2 h, the solvent was concentrated, and the precipitated solid was washed with diethyl ether to afford product 8 (65 g, 97.6%). 1H NMR (400 MHz, D2O) δ 3.70 (s, 3 H), 5.17 (s, 1 H), 7.35-7.41 (m, 5 H).
