Reaction Steps

A suspension of 4-{2-[4-(2-tert-butylphenyl)piperazin-1-yl]-2-oxoethyl}piperidine-2,6-dione (Example 14, 0.300 g, 0.81 mmol), benzyl bromoacetate (0.236 g, 0.97 mmol), and potassium carbonate (0.335 g, 2.42 mmol) in DMF (5 mL) was stirred at 60° C. for 16 h. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated sodium hydrogen carbonate solution and brine, dried over MgSO4, and the solvent was evaporated under reduced pressure to give a pale yellow powder, which was re-crystallized from hexane and ethyl acetate to provide benzyl (4-{2-[4-(2-tert-butylphenyl)piperazin-1-yl]-2-oxoethyl}-2,6-dioxopiperidin-1-yl)acetate (0.474 g, 79%) as an off-white powder.
