実験手順

A mixture of methyl N-[[2-chloro-5-(1H-pyrazol-3-yl)phenyl]methyl]carbamate (i.e. the product of Step B, Example 4) (0.2 g, 0.75 mmol), 1-(bromomethyl)-3-(trifluoromethoxy)benzene (0.765 g, 3.0 mmol) and potassium carbonate (−325 mesh, 0.829 g, 6.0 mmol) in N,N-dimethylformamide (4 mL) was heated at 100° C. overnight and then concentrated under reduced pressure. The resulting residue was purified by medium pressure liquid chromatography (0 to 100% gradient of ethyl acetate in hexanes as eluant) to provide the title compound, a compound of the present invention, as a solid (0.178 g).
