Procedure
3-Cyclopropylmethoxy-4-nitrotoluene (0.77 g, 75%) was prepared from cyclopropylmethanol and 3-fluoro-4-nitrotoluene (0.77 g, 5.0 mmol) following the general procedure G. This was reduced to 2-cyclopropylmethoxy-4-methyl-aniline (0.47 g, 71%) following general procedure C. 1-(2-Cyclopropylmethoxy-4-methyl-phenyl)-3-thiazol-2-yl-urea (218 mg, 72%) was prepared from 2-cyclopropylmethoxy-4-methyl-aniline (177 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
