Reaction Steps

Ethyl 3-iodobenzoate (857 mg, 3.10 mmol), DMF (5 mL), copper(I) iodide (65 mg, 0.34 mmol), N1,N2-dimethylaminoethylene (62.9 mg, 0.714 mmol), D-valine (400 mg, 3.41 mmol) and potassium carbonate (429 mg, 3.10 mmol) were charged into a flask. The flask was evacuated, then filled with nitrogen over several cycles to remove oxygen, then the reaction was heated to 140° C. under nitrogen for 4 hrs. The reaction was cooled, the DMF removed by evaporation, and 1 N HCl added. The reaction mixture was partitioned between EtOAc and water, and the organic layer was dried over sodium sulfate, filtered, and concentrated to yield a brown oil. This was used in next step without further purification.
