実験手順

To a solution of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide [WO 2005/002577] (50 mg, 0.092 mmol) in 0.5 mL of DMSO was added hexahydro-2H-pyrazino[1,2-a]pyrazin-1(6H)-one (D78, 33 mg, 0.213 mmol) and potassium carbonate (39 mg, 0.28 mmol) and the reaction was left at 150° C. for 24 h. It was worked up by diluting with dichloromethane and extracting with brine. The organics were dried (Na2SO4), and the solvent removed. The product was purified by flash chromatography: silica, cyclohexane:EtOAc 50:50 to EtOAc. Obtained 37 mg of the title compound.
