Reaction Steps

The title compound was prepared starting from 135 mg (0.253 mmoles) of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl) -3-pyridinyl]-N,2-dimethylpropanamide (WO 2005/002577), 70 mg (0.5 mmol) of (8aS) -hexahydropyrrolo[1,2-a]pyrazin-4(1H)-one (EP 300189), 70 mg (0.5 mmol) of potassium carbonate; the reagents were dissolved in 0.8 ml of DMSO. The reaction mixture was heated at 150° C. overnight and then added to a saturated NH4Cl solution and back extracted with DCM; the crude material was purified on SPE cartridge (Silica) eluting with a gradient cyclohexane/ethyl acetate 9:1, to ethyl acetate 100% and affording 24 mg of the title compound as pale yellow solid.
