実験手順

A mixture of 1-benzyl-3-bromomethyl-2-oxo-1,2-dihydro-pyridine-4-carboxylic acid ethyl ester (270 mg, 0.77 mmol), (toluene-4-sulfonylamino)-acetic acid methyl ester (210 mg, 0.85 mmol), sodium iodide (219 mg, 1.54 mmol) and potassium carbonate (213 mg, 1.54 mmol) in DMF (7 mL) was stirred at r.t. for 16 h. EtOAc (40 mL) and brine (10 mL) were added, and the aqueous layer was extracted with additional EtOAc. The organic layers were combined, washed with water and brine, and dried over MgSO4. After evaporating the solvent in vacuo, the crude product was chromatographed (0-70% EtOAc/hexanes) to give 232 mg of the title compound as a yellow oil. MS: (+) m/z 513.19 (M+1).
