実験手順
To a solution of diethyl 2-acetamido-2-(4-(trifluoromethyl)benzyl)malonate (LXII) (theoretical 0.125 mole) in acetone (400 mL) was added aq. 2 M NaOH (400 mL). The mixture was refluxed overnight before the solvent was removed under reduced pressure. The residue was taken up in water, washed with hexane (3×), acidified to pH=1 and filtered to produce 2-acetamido-3-(4-(trifluoromethyl)phenyl)propanoic acid (LXIII) as a white solid (25.8 g, 93.7 mmol, 75% yield after two steps).
