実験手順

3-(2,3-Dimethoxyphenoxy)-4-nitrotoluene (0.92 g, 64%) was prepared from 2,3-dimethoxyphenol (0.85 g, 5.5 mmol) and 3-fluoro-4-nitrotoluene (0.78 g, 5.0 mmol) following the general procedure A. This was reduced to 2-(2,3-dimethoxyphenoxy)-4-methylaniline (0.65 g, 79%) following general procedure C. N-[2-(2,3-Dimethoxyphenoxy)-4-methylphenyl]-N′-(thiazol-2-yl)urea (120 mg, 63%) was prepared from 2-(2,3-dimethoxyphenoxy)-4-methylaniline (130 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
