Reaction Steps

In an inert atmosphere, N—[(S)-1-benzyl-2-(4-benzyl-piperazin-1-yl)-2-oxo-ethyl]-N-(6-bromo-pyridin-3-ylmethyl)-3-(4-trifluoromethyl-phenyl)-acrylamide (70 mg, 0.101 mmol), 2-pyrrolidinon (10.3 mg, 0.121 mmol), potassium carbonate (27.9 mg, 0.202 mmol), copper(I)iodide (1 mg, 0.005 mmol) and N,N-dimethylenediamine (1 mg, 0.01 mmol) were dissolved in dioxane (1 mL). The reaction mixture was heated to 120° C. for 12 h, then filtered over a plug of silicagel with EtOAc, concentrated and purified by perp. HPLC to give 29 mg (52%) of N—[(S)-1-benzyl-2-(4-benzyl-piperazin-1-yl)-2-oxo-ethyl]-N-[6-(2-oxo-pyrrolidin-1-yl)-pyridin-3-ylmethyl]-3-(4-trifluoromethyl-phenyl)-acrylamide. (LC-MS: tR=1.02 min; [M+H]+=688.46).
