Procedure
3-(4-Fluoro-2-nitro-phenoxy)-benzoic acid methyl ester (0.73 g, 50%) was prepared from 3-hydroxy-benzoic acid methyl ester (0.84 g, 5.5 mmol) and 2,5-difluoro-1-nitro-benzene (0.80 g, 5.0 mmol) following the general procedure A. This was reduced to 2-(2-amino-4-fluoro-phenoxy)-benzoic acid methyl ester (0.37 g, 58%) following general procedure C. 3-[4-Fluoro-2-(3-thiazol-2-yl-ureido)-phenoxy]-benzoic acid methyl ester (145 mg, 75%) was prepared from 3-(2-amino-4-fluoro-phenoxy)-benzoic acid methyl ester (130 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
