Reaction Steps
4-Nitro-3-(tetrahydro-furan-2-ylmethoxy)-toluene (0.88 g, 75%) was prepared from tetrahydro-furan-2-ylmethanol and 3-fluoro-4-nitrotoluene (0.77 g, 5.0 mmol) following the general procedure G. This was reduced to 4-methyl-2-(tetrahydro-furan-2-ylmethoxy)-aniline (0.50 g, 65%) following general procedure C. 1-[4-Methyl-2-(tetrahydro-furan-2-ylmethoxy)-phenyl]-3-thiazol-2-yl-urea (236 mg, 71%) was prepared from 4-methyl-2-(tetrahydro-furan-2-ylmethoxy)-aniline (207 mg, 1.0 mmol) and 2-aminothiazole (100 mg, 1.0 mmol) following the general procedure D.
