実験手順

2-(4-Fluoro-2-nitro-phenoxy)-6-methoxy-benzoic acid methyl ester (0.94 g, 58%) was prepared from 2-hydroxy-6-methoxy-benzoic acid methyl ester (1.01 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)-6-methoxy-benzoic acid methyl ester (0.51 g, 60%) following general procedure C. 2-[4-Fluoro-2-(3-thiazol-2-yl-ureido)-phenoxy]-6-methoxy-benzoic acid methyl ester (129 mg, 62%) was prepared from 2-(2-amino-4-fluoro-phenoxy)-6-methoxy-benzoic acid methyl ester (145 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
