Versuchsvorschrift

To a suspension of the compound prepared in Example 191 (10.0 g) in acetonitrile (70 ml) was added phosphorus oxychloride (7.04 ml) and the resulting mixture was stirred at 90° C. for two hours. The mixture was concentrated on evaporator instrument under reduced pressure and to the residue were then added ethyl acetate (50 ml) and hexane (50 ml) and the mixture was stirred for thirty minutes. The precipitated solids were collected by filtration and washed with ethyl acetate/hexane=1/1 to afford 1-(4-cyanophenyl)-5-(3,6-dimethyl-2,4-dioxo-1-(3-trifluoromethylphenyl)-1,2,3,4-tetrahydropyrimidin-5-yl)-1H-pyrazole-4-sulfonylchloride (10.3 g). UPLC/MS 550 (M+H)/1.08 min. (measurement condition 9).
