---|---|---|
To a stirred solution of l-methyl-6-oxo-l,6-dihydropyridine-3-carboxamide (460 mg, 3.02 mmol) in 20 mL of CH2C12 was added TEA (0.548 mL, 3.93 mmol) at 0 C. The reaction mixture was stirred for 10 min and then triflic anhydride was added (1.0 M in CH2C12, 3.33 mL, 3.33 mmol). Removed ice bath and stirred at ambient temperature for 3 h. The reaction was quenched with water and saturated aqueous sodium chloride. The aqueous layer was extracted with CH2C12 (3x's). The combined organic layers were then dried over sodium sulfate and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of hexanes: ethyl acetate (95:5 to 15:85), to give the title compound. MS: m/z = 135.0 [M+l]+. |
