Reaktionsschritte
2-(2,3-Dimethoxyphenoxy)-5-fluoro-1-nitrobenzene (1.0 g, 68%) was prepared from 2,3-dimethoxyphenol (0.85 g, 5.5 mmol) and 2,5-difluoro-1-nitrobenzene (0.80 g, 5.0 mmol) following the general procedure A. This was reduced to 2-(2,3-dimethoxyphenoxy)-5-fluoro-aniline (0.67 g, 75%) following general procedure C. N-[2-(2,3-Dimethoxyphenoxy)-5-fluoro-phenyl]-N′-(thiazol-2-yl)urea (126 g, 65%) was prepared from 2-(2,3-dimethoxyphenoxy)-5-fluoroaniline (132 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
