반응 단계

A mixture of 20 g (0.16 mole) of β-chlorolactic acid and 86 g (0.48 mole) of 3,4-dimethoxyphenethylamine was heated at 110° C. for 15 hours. The resulting product was dissolved in about 200 ml of water and the pH was adjusted to about 8 with Na2CO3. The aqueous solution was extracted with 2×500 ml of chloroform and neutralized to pH 7 with diluted HCl. The solution was evaporated to dryness and the residue was recrystallized in EtOH to give 24.6 g (61.6%) of crystals: m.p. 187.5°-188.5° C. The NMR, IR and mass spectra were consistent with the assigned structure, and the elemental analysis was consistent with the empirical formula, C13H19O5N.
