A mixture of 1-benzyl-2-bromomethyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (2.4 g, 7.14 mmol), (toluene-4-sulfonylamino)-acetic acid methyl ester (1.74 g, 7.14 mmol), sodium iodide (2.14 g, 14.3 mmol) and potassium carbonate (1.97 g, 14.3 mmol) in DMF (45 mL) was stirred at r.t. for 16 h. Brine (100 mL) and EtOAc (100 mL) were added and the aqueous layer was extracted several times with EtOAc. The organic layers were combined, washed with water, and dried over MgSO4. After the solvent was evaporated in vacuo, the crude product was chromatographed (0-75% EtOAc/hexanes) to give 1.95 g of the title compound as a yellow oil. MS: (+) m/z 499.06 (M+1).
