Procedure

2-(3,4-Dichlorophenoxy)-1-nitrobenzene (1.15 g, 81%) was prepared from 3,4-dichlorophenol (0.9 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-(3,4-dichlorophenoxy)aniline (0.69 g, 68%) following general procedure B. N-[2-(3,4-Dichlorophenoxy)phenyl]-N′-(thiazol-2-yl)urea (129 mg, 68%) was prepared from 2-(3,4-dichlorophenoxy)aniline (127 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
