Procedure

The title compound was prepared starting from 100 mg (0.188 mmoles) of 1-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]cyclopropanecarboxamide (D2), 70 mg (0.554 mmol) of (8aS)-octahydropyrrolo[1,2-a]pyrazine, 52.2 mg (0.377 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 dichloromethane; the crude material was purified on SPE cartridge (Silica) eluting with a gradient from cyclohexane/ethyl acetate 1:1, to ethyl acetate 100%, affording 72 mg of the title compound as pale yellow solid.
