Reaction Steps
5-Fluoro-2-(naphth-2-oxy)-1-nitrobenzene (1.13 g, 80%) was prepared from 2-naphthol (0.79 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-(2-naphth-2-oxy)-5-fluoroaniline (0.64 g, 64%) following the general procedure B. N-[5-Fluoro-2-(naphth-2-oxy)phenyl]-N′-(thiazol-2-yl)urea (123 mg, 65%) was prepared from 5-Fluoro-2-(naphth-2-oxy)-aniline (127 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
