Procedure

The title compound was prepared starting from 250 mg (0.47 mmole) of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide (WO 2005/002577), (8aR)-hexahydropyrrolo[1,2-a]pyrazin-4(1H)-one (D4), 164.4 mg (1.17 mmol), 130 mg of potassium carbonate (0.94 mmol); the reagents were dissolved in 1.5 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 115 mg of the title compound as pale yellow solid.
