Reaction Steps
A solution of 3-[3-(bromomethyl)-1,2-benzisothiazol-5-yl]-1-methyl-6-(trifluoromethyl)-2,4(1H,3H)-pyrimidinedione (0.750 g, 1.79 mmol) in 1,2-dichloroethane is diluted with methanol, treated with silver trifluoromethanesulfonate (0.610 g, 2.37 mmol), stirred overnight at room temperature, and filtered through diatomaceous earth. The resultant filtrate is washed with saturated sodium hydrogen carbonate solution, dried over anhydrous magnesium sulfate, and concentrated in vacuo to obtain a solid. Column chromatography of the solid using silica gel, and 2% and 5% diethyl ether in methylene chloride solutions gives the title product as a white solid (0.600 g, mp 161-163° C.) which is identified by 1H NMR spectral analysis.
