The reaction mixture was then cooled in an ice bath before HCL (82 ml, 3M) was added dropwise. This was allowed to stir at room temperature for 3 hr. The mixture was then put in the freezer over the weekend. The reaction was then warmed to room temperature and extracted with ether. The aqueous layers were washed twice more with ether. The combined organic layers were washed three times with 5M NaOH aqueous solution. The combined basic layers were acidified to pH=1 with 6M HCL solution. These acidified layers were then extracted three times with ether. These ether layers were then dried over MgSO4, filtered, then concentrated in vacuo to about 50 ml solution. To this solution was added hexanes and a minimal amount of ethyl acetate. A white precipitate is observed and the mixture in stored in the freezer to allow for crystallization. The white solid is then filtered and collected (14.65 g, 57mml, 70%) ES-MS(M+H)+=258.

At the end of this time, the catalyst was removed by filtration, and the filtrate was washed with diethyl ether. The aqueous phase was then concentrated by evaporation under reduced pressure. The resulting residue was subjected to column chromatography (Cosmosil 75C18 -prep, manufactured by Nacalai Tesque, 18 ml). Of the fractions obtained by elution with water, the one containing the title compound was concentrated by evaporation under reduced pressure and freeze-dried to give 46 mg of the title compound as a powder.

Procedure:
4-Nitro-(1',1',2',2'-tetrafluoroethoxy-benzene was converted to 4-(1',1',2',2'-tetrafluoroethoxy)-aniline using the general procedure illustrated in Preparation 12 of EP 0 398 499. In such Preparation, reduced iron powder (0.18 g) was added to a suspension of 1-(2-fluoro-6-nitro-4-trifluoromethylphenyl)-4-trifluoromethylpyrimidin-6-one (0.6 g) in a mixture of isopropanol (6 ml) and water (0.6 ml). Concentrated hydrochloric acid (1 drop) was added, and the reaction mixture was heated to 100° C. for a period of 5 hours. After cooling to ambient temperature, the reaction mixture was filtered through celite, and the residue washed with ethyl acetate. Evaporation of the filtrate under reduced pressure gave 1-(2-amino-6-fluoro-4-trifluoromethylphenyl)-4-trifluoromethylpyrimidin-6-one.
