Reaction Steps

2-(3,4-Difluorophenoxy)-5-fluoro-1-nitrobenzene (1.05 g, 78%) was prepared from 3,4-difluorophenol (0.72 g, 5.5 mmol) and 2,5-difluoro-1-nitrobenzene (0.8 g, 5.0 mmol) following the general procedure A. This compound was reduced to 2-(3,4-difluorophenoxy)-5-fluoroaniline (0.63 g, 68%) following the general procedure B. N-[2-(3,4-Difluorophenoxy)-5-fluorophenyl]-N′-(thiazol-2-yl)urea (132 mg, 72%) was prepared from 2-(3,4-difluorophenoxy)-5-fluoroaniline (120 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
