Participants

Reaction Steps

5-Fluoro-2-(2-methylpropoxy)-4-nitrobenzene (0.83 g, 78%) was prepared from 2-methylpropanol (0.46 ml, 5.0 mmol) and 2,5-difluoro-4-nitrobenzene (0.80 g, 5.0 mmol) following the general procedure G. This was reduced to 5-fluoro-2-(2-methylpropoxy)-aniline (0.58 g, 81%) following general procedure C. 1-(5-Fluoro-2-isobutoxy-phenyl)-3-thiazol-2-yl-urea (220 mg, 72%) was prepared from 5-fluoro-2-(2-methylpropoxy)-aniline (183 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
