Versuchsvorschrift

2-(Cyclopentylmethoxy)-1-nitrobenzene (443 mg, 80%) was prepared from cyclopentanemethanol (0.32 ml, 3.0 mmol) and 1-fluoro-2-nitrobenzene (0.36 g, 2.5 mmol) following the general procedure G. This was reduced to 2-(cyclopentylmethoxy)aniline (268 mg, 70%) following general procedure B. N-[2-(Cyclopentylmethoxy)phenyl]-N′-(thiazol-2-yl)urea (286 mg, 60%) was prepared from 2-(cyclopentylmethoxy)aniline (0.25 g, 1.5 mmol) and 2-aminothiazole (150 mg, 1.5 mmol) following the general procedure D.
