Reaction Steps

A mixture of 1-methyl-3-(3-methyl-1,2-benzisothiazol-5-yl)-6-(trifluoromethyl)-2,4(1H,3H)-pyrimidinedione (1.00 g, 0.00293 mol), sulfuryl chloride (2.00 g 0.0148 mol) and 1,2-dichloroethane is stirred for five hours at reflux, cooled to room temperature, and diluted with methylene chloride. The resultant mixture is washed with saturated sodium bicarbonate and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to obtain a residue. The residue is chromatographed on silica gel with ethyl acetate/hexanes to afford the title product as a white solid (0.350 g, 31.8%, mp 252-254° C.) which is identified by NMR spectral analysis.
