Versuchsvorschrift

N-methyl-N-[2-(methylphenyl)benzoyl]glycine ethyl ester (4.5 g, 14.45 mmol) and KOH (2.43 g, 43.4 mmol) in MeOH/H2O (200 mL/50 mL) were heated at reflux for 45 minutes. The solvent was removed and the residue dissolved in H2O. The aqueous solution was washed with Et2O and acidified with HCl (10%). The acidified aqueous layer was extracted with EtOAc, the EtOAc extract was washed with brine (2×), dried over (MgSO4) and evaporated. There was obtained N-methyl-N-[2-(methylphenyl)benzoyl]glycine (2.0 g); LRMS (M+H)+=284.1, (M+NH4)+=301.1
