Versuchsvorschrift

5-[(2,4-Dioxothiazolidin-5-yl)methyl]-2-methoxybenzoic acid (282 mg, 1.00 mmol), 2-picolylamine (114 mg, 1.05 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (230 mg, 1.20 mmol) and N,N-dimethylformamide (5 mL) were mixed and stirred for 5.5 hours at room temperature, which was then allowed to stand overnight. After water was added to the reaction mixture, this was made acidic and extracted with ethyl acetate. The extracted solution was dried and then concentrated. The residue was recrystallized from acetonitrile to obtain 73.7 mg (20%) of the title compound as colorless crystals.
