Participants

Reaction Steps

1.0 M lithium bis(trimethylsilyl)amide (100 μl, 0.1 mmol, Aldrich) was slowly added to a solution of 2-fluoro-N-1H-pyrazol-3-ylbenzamide (for a preparation see Intermediate 43) (20.5 mg, 0.1 mmol) in THF (400 μl). The resulting solution was then transferred to a solution of 1-(bromomethyl)-4-(methyloxy)-2-(trifluoromethyl)benzene 24.7 mg, 0.1 mmol, JRD Fluorochemicals Ltd) in THF (200 μl) and stirred for 2 h under nitrogen at ambient temperature. The mixture was diluted with DMSO (0.6 ml) and purified by MDAP using the Sunfire C18 column (Method D) using Acetonitrile-Water with a TFA modifier. The solvent was removed under a stream of nitrogen to give the title compound (27 mg). LCMS (System 4)
