Participants

Reaction Steps

A mixture of 2-ethoxy-3-[3-(6-hydroxy-m-tolyl)-1,2-benzisothiazol-5-yl]-6-(trifluoromethyl)-4(3H)-pyrimidinone (0.470 g, 1.05 mmol), potassium carbonate (0.190 g, 1.37 mmol) and methyl bromoacetate (0.210 g, 1.37 mmol) in N,N-dimethylformamide is stirred overnight at room temperature, diluted with ethyl acetate, washed sequentially with water and brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to obtain a solid. Flash column chromatography of the solid using silica gel and a 10% diethyl ether in methylene chloride solution gives the title product as an off-white solid (0.450 g, mp 171-174° C.).
