실험 절차

The title compound was prepared starting from 100 mg (0.187 mmoles) of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl) -3-pyridinyl]-N,2-dimethylpropanamide (WO 2005/002577), 79 mg (0.563 mmol) of (8aR) -hexahydropyrrolo[1,2-a]pyrazin-3(4H)-one (D14), 72 mg of copper iodide (0.378 mmol), 40 μl (0.375 mmol) of N,N-dimethylmethanediamine, 112.4 mg (0.375 mmol) of cesium carbonate; the reagents were dissolved in 4 ml of dioxane and heated at 80° C. for 4 h and then at 120° C. overnight. The crude material was purified on SPE cartridge (Silica) eluting with a gradient from cyclohexane/ethyl acetate 9:1, to ethyl acetate 100% and affording 60 mg of the title compound as pale yellow solid.
