To a mixture of 2,6-difluoro-N-(1H-pyrazol-3-yl)benzamide (for a preparation see Intermediate 9) (0.360 g, 1.61 mmol) and potassium carbonate (0.308 g, 2.23 mmol) was added a solution 2-(bromomethyl)-1-chloro-3-[(phenylmethyl)oxy]benzene (for a preparation see Intermediate 8)(0.50 g, 1.61 mmol) in DMF (5 ml). The suspension was stirred overnight at ambient temperature. The suspension was partitioned between ethyl acetate (30 ml) and water (30 ml). The phases were separated and the organic phase washed with ethyl acetate (30 ml). The combined organic extracts were washed with brine (30 ml) and the solvent removed in vacuo. The residue was loaded in dichloromethane and purified on silica 50 g using 0-50% ethyl acetate-cyclohexane. The appropriate fractions were combined and evaporated in vacuo to give the title compound as a white solid (0.212 g); LCMS: (System 1) MH+=455, tRET=3.59 min.
