Procedure

A mixture of 5-bromo-2-bromomethyl-6-oxo-1-thiazol-2-ylmethyl-1,6-dihydro-pyridine-3-carboxylic acid methyl ester (100 mg, 0.24 mmol), (toluene-4-sulfonylamino)-acetic acid methyl ester (58 mg, 0.24 mmol), sodium iodide (71 mg, 0.47 mmol) and potassium carbonate (66 mg, 0.47 mmol) in DMF (5 mL) was stirred at r.t. for 16 h. Brine was added, and the resulting mixture was extracted with EtOAc. The organic layer was washed with water and brine, and dried over MgSO4. After the solvent was evaporated in vacuo, the crude product was chromatographed (0-60% EtOAc/hexanes) to give 41 mg of the title compound as a viscous oil. MS: (+) m/z 584.14, 586.09 (M+1, 79/81Br).
