実験手順

2-[2-(Trifluoromethyl)phenoxy]-1-nitrobenzene (0.92 g, 65%) was prepared from 2-hydroxybenzotrifluoride (0.89 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-(trifluoromethyl)phenoxy]aniline (0.56 g, 68%) following general procedure B. N-[2-(2-Trifluoromethylphenoxy)phenyl]-N′-(thiazol-2-yl)urea (115 mg, 61%) was prepared from 2-[2-(trifluoromethyl)phenoxy]aniline (127 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
