Procedure

3-(3-Methyl-butoxy)-4-nitrotoluene (0.89 g, 80%) was prepared from 3-methylbutanol and 3-fluoro-4-nitrotoluene (0.77 g, 5.0 mmol) following the general procedure G. This was reduced to 4-methyl-2-(3-methylbutoxy)aniline (0.55 g, 72%) following general procedure C. 1-[4-Methyl-2-3-methyl-butoxy)-phenyl]-3-thiazol-2-yl-urea (240 mg, 76%) was prepared from 4-methyl-2-(3-methyl-butoxy)aniline (193 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
