Procedure

Reduced iron powder (0.18g) was added to a suspension of 1-(2-fluoro-6-nitro-4-trifluoromethylphenyl)-4-trifluoromethylpyrimidin-6-one (0.6g) in a mixture of isopropanol (6ml) and water (0.6ml). 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 as an off-white solid, which was used in Preparation 13 without further purification.
