Versuchsvorschrift

A 8 ml sealed vial was charged with 180 mg (0.31 mmol) of 2-[3,5-bis(trifluoromethyl)phenyl]N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide (WO 2005/002577); 168 mg (0.62 mmol) of octahydropyrazino[2,1-c][1,4]thiazine 2,2-dioxide (D19), 128 mg (0.701 mmol) of potassium carbonate; the reagents were dissolved in 1 ml of DMSO and stirred at 150° C. for 18 h. The reaction mixture was diluted with water and ethyl acetate and the aqueous phase was extracted with ethyl acetate. The combined organic fractions were dried and the solvent was removed under reduced pressure. The crude product was purified by flash chromatography (silica, cyclohexane/EtOAc 50/50 to EtOAc) affording the title compound as a white solid 105 mg.
