Procedure

To a suspension of 3-(4-pyridin-4-yl-1H-pyrazol-3-yl)-phenylamine (80 mg, 0.339 mmol) (prepared as described in Example 6) in dichloromethane (8 mL), were added in the following order: (4-trifluoromethyl-phenyl)-acetic acid (138 mg, 0.678 mmol), DIPEA (131 mg, 174 uL, 1.017 mol) and TBTU (326 mg, 1.017 mol). The reaction mixture was stirred at room temperature for 4 hours. Then it was poured into a solution of saturated NaHCO3, the phases separated, and the organic phase was washed twice with saturated NaHCO3, and twice with water. The organic solvent was evaporated, and the residue taken up with methanol (5 mL). TEA (2 mL) was added, and the solution was stirred at room temperature overnight. After evaporation to dryness the compound was purified by flash chromatography, over silica gel, using dichloromethane-methanol (97:3) as the eluant system. N-[3-(4-Pyridin-4-yl-1H-pyrazol-3-yl)-phenyl]-2-(4-trifluoromethyl-phenyl)-acetamide was obtained as a colorless solid (125 mg, 87%).
