Versuchsvorschrift

2-(2,3-Dimethoxyphenoxy)-3-nitrotoluene (0.80 g, 56%) was prepared from 2,3-dimethoxyphenol (0.85 g, 5.5 mmol) and 2-chloro-3-nitrotoluene (0.85 g, 5.0 mmol) following the general procedure A. This was reduced to 2-(2,3-dimethoxyphenoxy)-3-methylaniline (0.54 g, 76%) following general procedure C. N-[2-(2,3-Dimethoxyphenoxy)-3-methylphenyl]-N′-(thiazol-2-yl)urea (116 mg, 61%) was prepared from 2-(2,3-dimethoxyphenoxy)-3-methylaniline (130 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
