Versuchsvorschrift

Heat at reflux for 3 hours a mixture of N-trifluoroacetyl-L-glutamic anhydride (18.0 g, 80 mmol) and AlCl3 (23.5 g, 177 mmol) in dry benzene (400 ml). Allow to cool, treat with ice (400 ml), conc. HCl (100 ml), and ethyl acetate (EtOAc) (400 ml). Dry the organic layer and concentrate to obtain the title compound as a brown crystalline solid (25 g).
