실험 절차

To methyl 3-(dimethylamino)-2-(thiophen-3-yl)propanoate (E42) in THF/H2O/MeOH was added LiOH*H2O, and the solution was stirred for 12 hours. AcOH was added and the solvents were evaporated. Column chromatography (SiO2, 10-15% 2M NH3-MeOH/EtOH) gave pure 3-(dimethylamino)-2-(thiophen-3-yl)propanoic acid (E43).
