실험 절차
To a cooled suspension of 2(S)-benzyloxycarbonylamino-3-aminopropionic acid (Fluka) (23-1) (10 g, 0.042 mol) in 150 ml of methanol was added 5.47 g (0.046 mol) of thionyl chloride over 20 minutes. The resulting solution was allowed to stir at room temperature overnight. After ~18 hrs, the solvent was removed in vacuo, and the residual solid was stirred with 150 ml of ether for 0.5 hr. The resulting white solid was collected and air dried to give 23-2.
