Reaction Steps

5-Fluoro-2-(4-fluorophenoxy)-1-nitrobenzene (0.94 g, 75%) was prepared from 4-fluorophenol (0.62 g, 5.5 mmol) and 2,5-difluoro-1-nitrobenzene (0.71 g, 5.0 mmol) following the general procedure A. This compound was reduced to 2-(4-fluorophenoxy)-5-fluoroaniline (0.53 g, 64%) following the general procedure B. N-[5-Fluoro-2-(4-fluorophenoxy)phenyl]-N′-(thiazol-2-yl)urea (130 mg, 75%) was prepared from 5-fluoro-2-(4-fluorophenoxy)aniline (110 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
