実験手順

2-(4-Chlorophenoxy)-1-nitrobenzene (0.88 g, 71%) was prepared from 4-chlorophenol (0.70 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-(4-chlorophenoxy)aniline (0.50 g, 65%) following general procedure B. N-[2-(4-Chlorophenoxy)phenyl]-N′-(thiazol-2-yl)urea (106 mg, 62%) was prepared from 2-(4-chlorophenoxy)aniline (109 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
