Procedure
A mixture of one equivalent of 3-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidin-1-yl)phenoxy]-3-(methylsulfonyl)-3,4-dihydro-1H-pyridin-2-one, 0.1 equivalent of p-toluenesulsonic acid and toluene is refluxed under stirring. After the reaction, the reaction liquid is concentrated and the residue is subjected to silica gel column chromatography to give 3-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidin-1-yl)phenoxy]-1H-pyridin-2-one.
