Procedure
To a solution of 2-(4-(2-(trifluoromethoxy)phenyl)pyridin-3-ylamino)acetonitrile (0.07 g, 239 μmol) in CH2Cl2 (2 mL) were added 3-(methylsulfonyl)-5-(trifluoromethyl)benzoyl chloride (137 mg, 477 μmol, example 223, intermediate d) and DIPEA (123 mg, 167 μL, 955 μmol) and the clear, yellow solution was stirred at room temperature for 18 hours. The reaction mixture was poured on saturated aqueous NH4Cl solution and CH2Cl2 and the layers were separated. The aqueous layer was extracted three times with CH2Cl2. The organic layers were dried over MgSO4, filtered, treated with silica gel and evaporated. The compound was purified by silica gel chromatography on a 20 g column using a MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). The product was purified by preparative HPLC (Gemini NX column) using a gradient of MeOH:water (containing 0.1% formic acid) (20:80 to 98:2). Colorless solid (0.085 g; 65%). MS (ESI): m/z=544.08 [M+H]+.
