Procedure

A mixture of 5-bromo-2-bromomethyl-1-methyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (363 mg, 1.07 mmol), (toluene-4-sulfonylamino)-acetic acid methyl ester (260 mg, 1.07 mmol), sodium iodide (321 mg, 2.14 mmol) and potassium carbonate (296 mg, 2.14 mmol) in DMF (10 mL) was stirred at r.t. for 16 h. Brine (30 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 (0-70% EtOAc/hexanes) to give 292 mg of the title compound. MS: (+) m/z 501.13, 503.08 (M+1, 79/81Br).
