After stirring for 10 minutes, 1-hydroxybenzenetriazole (0.35 g, 2.6 mmol) and <strong>[5162-82-3]3-chloro-4-methyl-benzoic acid</strong> (0.4 g, 2.4 mmol) were added. To the reaction mixture, was then added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.62 g, 3.2 mmol), and the mixture was stirred at room temperature overnight. The reaction mixture was then concentrated in vacuo, and the residue was stirred in H2O (50 mL). A suspension formed and after filtration the solid was reslurried in acetone (20 mL). The suspension was filtered to afford 3-chloro-N-[2-(2,6-dioxo-piperidin-3-yl)-1,3-dioxo-2,3-dihydro-1H-isoindol-4-ylmethyl]-4-methyl-benzamide as a white solid (0.75 g, 79%): mp, 249-251 C.; HPLC: Waters Symmetry C-18, 3.9×150 mm, 5 micro, 1 mL/min, 240 nm, 40/60 (CH3CN/H2O): tR=6.8 min.
