Procedure

2-(2,4-Difluorophenoxy)-1-nitrobenzene (0.95 g, 76%) was prepared from 2,4-difluorophenol (0.72 g, 5.5 mmol) and 1-fluoro-2-nitrobenzene (0.71 g, 5.0 mmol) following the general procedure A. This was reduced to 2-(2,4-difluorophenoxy)aniline (0.53 g, 63%) following general procedure B. N-[2-(2,4-Difluorophenoxy)phenyl]-N′-(thiazol-2-yl)urea (120 mg, 69%) was prepared from 2-(2,4-difluorophenoxy)aniline (110 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
