実験手順
Methyl iodide (0.15 mL, 2.41 mmol) and potassium carbonate (0.19 g, 1.34 mmol) are added to a solution of methyl 3-[5-(2,4-dichlorophenoxy)-2-nitrophenyl]tetrahydro-2,4,6-trioxo-s-triazine-1(2H)-acetate (0.40 g, 0.83 mmol) in N,N-dimethylformamide. The reaction mixture is stirred overnight at room temperature and poured into a saturated ammonium chloride solution. The aqueous mixture is extracted with ethyl acetate. The organic extracts are combined, washed sequentially with water and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo to obtain a yellow oil. Column chromatography of the oil using silica gel and an ethyl acetate/hexanes (1:3) solution gives the title product as a yellow foam which is identified by NMR spectral analysis.
