Procedure

To a mixture of 2,6-difluoro-N-1H-pyrazol-3-ylbenzamide (for as preparation see Intermediate 9) (76 mg, 0.340 mmol) and potassium carbonate (96 mg, 0.692 mmol) was added a solution of 1-(bromomethyl)-4-chloro-2-[(phenylmethyl)oxy]benzene (0.106 g, 0.340 mmol) in DMF (1 ml). The reaction was stirred overnight, at ambient temperature and under nitrogen. The suspension was filtered using a hydrophobic frit and the residue washed with methanol (1 ml). The filtrate was purified by MDAP (supelcosil ABZ+Plus column) eluting with solvents A/B (A: Water+0.1% Formic acid, B: MeCN:Water 95:5+0.05% Formic acid) (Method A). The solvent was evaporated in vacuo to give the title compound as a white solid (27 mg); LCMS: (System 1) MH+=454, tRET=3.68 min.
