Participants

Reaction Steps

4-Trifluoromethylbenzoylchloride (0.054 g, 0.26 mmol) was added to a solution of 3-[4-pyridin-4-yl-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazol-3-yl]-benzylamine (0.10 g, 0.26 mmol) (prepared as described in Example 17) and triethylamine (0.08 g, 0.79 mmol) in dry DCM (2.0 ml) at 0° C. The reaction mixture was stirred at room temperature under nitrogen atmosphere for 6 h. The organic layer was washed with water (2.0 mL) and dried over Na2SO4. The filtrate was evaporated to dryness to give an oil which was purified by flash chromatography, over silica gel, using dichloromethane/MeOH (98:0.2) as eluent, to afford N-{3-[4-pyridin-4-yl-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazol-3-yl]-benzyl}-4-trifluoromethyl-benzamide (0.110 g, 0.20 mmol, 76%).
