Versuchsvorschrift

2-[4-Methoxy-2-methoxycarbonylphenoxy]-1-nitrobenzene (0.78 g, 52%) was prepared from methyl 5-methoxysalicylate (1.0 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-methoxy-2-(methoxycarbonyl)phenoxy]aniline (0.47 g, 68%) following general procedure B. N-[2-(4-Methoxy-2-methoxycarbonylphenoxy)phenyl]-N′-(thiazol-2-yl)urea (130 mg, 66%) was prepared from 2-[4-methoxy-2-(methoxycarbonyl)phenoxy]aniline (136 mg, 0.5 mmol) and 2-aminothiazole (60 mg, 0.6 mmol) following the general procedure D.
