Procedure

To 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), trans-N,N′-dimethylcyclohexane-1,2-diamine (0.043 g, 0.3 mmol), copper(I) iodide (0.03 g, 0.15 mmol) and potassium carbonate (−325 mesh) (0.622 g, 4.5 mmol) in dioxane (4 mL) was added 1-chloro-4-iodobenzene (0.27 g, 1.13 mmol). The reaction mixture heated at reflux 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 (0.156 g) melting at 151-153° C.
