Procedure

A mixture of 5-bromo-2-bromomethyl-6-oxo-1-phenethyl-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (320 mg, 0.746 mmol), (toluene-4-sulfonylamino)-acetic acid methyl ester (200 mg, 0.821 mmol), sodium iodide (212 mg, 1.49 mmol) and potassium carbonate (206 mg, 1.49 mmol) in DMF (7 mL) was stirred at r.t. for 16 h. Brine (50 mL) was added and the mixture was extracted with EtOAc. The organic layer was washed with water and dried over MgSO4. After the solvent was evaporated in vacuo, the crude product was chromatographed (0-60% EtOAc/hexanes) to give 371 mg of the title compound. MS: (+) m/z 591.13, 593.08 (M+1, 79/81Br).
