Methyl iodide → 1-Methyl-3-[3-(1-methylpyrrol-2-yl)-1,2-benzisothiazol-5-yl]-6-(trifluoromethyl)uracil

Participants

Reaction Steps

To a mixture of 3-[3-(1-methylpyrrol-2-yl)-1,2-benzisothiazol-5-yl]-6-(trifluoromethyl)uracil(1.35 g, 3.44 mmol), dry dimethylformamide and potassium carbonate (0.710 g, 5.14 mmol) is added iodomethane (0.730 g, 5.14 mmol). The resultant mixture is stirred overnight at room temperature and poured into ice water. Filtration and drying affords the title compound as a pink foam (0.300 g, 21.4%) which is identified by NMR spectral analysis.
