The title compound was prepared starting from 100 mg (0.161 mmoles) of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide (WO 2005/002577), 85 mg (0.483 mmol) of hexahydro-2H-isothiazolo[2,3-a]pyrazine 1,1-dioxide (D10), 44.5 mg (0.322 mmol) of potassium carbonate; the reagents were dissolved in 0.8 ml of DMSO. The reaction mixture was heated at 180° C. for 36-48 hrs 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 from cyclohexane/ethyl acetate 9:1, to cyclohexane/ethyl acetate 1:1 and affording 80 mg of the title compound as pale yellow solid.
