Versuchsvorschrift

To a stirred suspension of 4-aminomethyl-2-(2,6-dioxo-piperidin-3-yl)-isoindole-1,3-dione hydrochloride (0.7 g, 2.2 mmol) in acetonitrile (60 mL), was added 1,8-diazabicyclo[5,4,0]undec-7-ene (0.8 g, 5.4 mmol). After stirring for 10 minutes, 1-hydroxybenzotriazole (0.4 g, 2.6 mmol) and 3-(trifluoromethyl)phenylacetic acid (0.6 g, 2.4 mmol) were added, followed by 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.6 g, 3.2 mmol). The mixture was stirred at room temperature overnight then was concentrated in vacuo. The residue was dissolved in CH2Cl2 (80 mL) and washed with water (40 mL), 1NHCl (2×30 mL), water (40 mL), and brine (40 mL), and dried over MgSO4. Solvent was removed in vacuo, and the residue was purified by ISCO silica gel flash chromatography (Eluent: EtOAc: CH2Cl2 3:7) to afford N-[2-(2,6-dioxo-piperidin-3-yl)-1,3-dioxo-2,3-dihydro-1H-isoindol-4-ylmethyl]-2-(3-trifluoromethyl-phenyl)-acetamide (0.7 g, 70%) as a white solid: mp 156-158° C.; HPLC: Waters Symmetry C-18, 3.9×150 mm, 5 micro, 1 mL/min, 240 nm, 40/60 (CH3CN/H2O): tR=5.36 min.
