Versuchsvorschrift

3-Cyclopentylmethoxy-4-nitrotoluene (0.82 g, 70%) was prepared from cyclopentylmethanol and 3-fluoro-4-nitrotoluene (0.77 g, 5.0 mmol) following the general procedure G. This was reduced to 2-cyclopentylmethoxy-4-methyl-aniline (0.58 g, 81%) following general procedure C. 1-(2-Cyclopentylmethoxy-4-methyl-phenyl)-3-thiazol-2-yl-urea (225 mg, 68%) was prepared from 2-cyclopentylmethoxy-4-methyl-aniline (205 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
