실험 절차
A mixture of (+)-(1S,2R)-2-benzamidocyclohexanecarboxylic acid (4.0 g, 16.2 mmol, TCI chemical company) and 6 M hydrochloric acid (200 mL) was heated at reflux for 48 h. The reaction mixture was cooled to room temperature and extracted with diethyl ether (2×200 mL). The aqueous portion was concentrated in vacuo to afford (1S,2R)-2-aminocyclohexanecarboxylic acid as a white solid. The crude product was used in the next step without purification or characterization.
