Versuchsvorschrift

To a solution of 4-(2-chlorophenyl)-6-methyl-N-(2,2,2-trifluoroethyl)pyridin-3-amine (0.066 g, 219 μmol) and 3-(methylsulfonyl)-5-(trifluoromethyl)benzoyl chloride (66.1 mg, 230 μmol, example 223, intermediate d) in CH2Cl2 (1 mL) was added DIPEA (56.7 mg, 76.7 μL, 439 μmol) and the clear yellow solution was stirred at room temperature for 4 hours. Another batch of 3-(methylsulfonyl)-5-(trifluoromethyl)benzoyl chloride (66.1 mg, 230 μmol, example 223, intermediate d) and DIPEA (56.7 mg, 76.7 μL, 439 μmol) were added and stirring was continued for another 48 hours. The compound was purified by silica gel chromatography on a 20 g column using an MPLC (ISCO) system eluting with EtOAc (isocratic). The product was further purified by preparative HPLC (Gemini NX column) using a gradient of MeOH:water (containing 0.1% formic acid) (20:80 to 98:2). Light brown solid (5%). MS (ESI): m/z=551.06 [M+H]+.
