Procedure

2-(4-Cyanophenoxy)-1-nitrobenzene (0.82 g, 69%) was prepared from 4-cyano-phenol (0.66 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-cyanophenoxy)aniline (0.47 g, 65%) following general procedure B. N-[2-(4-Cyanophenoxy)phenyl]-N′-thiazolylurea (110 mg, 65%) was prepared from 2-(4-cyanophenoxy)aniline (105 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
