الإجراء التجريبي
To a solution of cis-1-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)octahydropyrrolo[1,2-a]pyrazine (D73, 50 mg) in dry toluene (0.5 mL), a solution of 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide [WO 2005/002577] (75 mg) in dry toluene (0.5 mL) was added at rt. Hexadecyltrimethylammonium chloride (25% aqueous solution, 132 microL), bis(tri-tert-butyl phosphine) palladium (19 mg) and NaOH (50% aqueous solution, 245 microL) were added. The resulting mixture was degassed by two freeze-thaw cycles and allowed to reach rt under a nitrogen atmosphere. The mixture was then heated at 90° C. for 5 hours. The mixture was allowed to cool down to rt, diluted with ethyl acetate (1 mL) and washed with a saturated solution of NaHCO3 (1 mL). The aqueous phase was extracted with ethyl acetate (3×2.5 mL). The combined organic extracts were dried and concentrated in vacuo to a residue which was purified by flash chromatography (Cycl/EtOAc 1:1) to give the desired compound (10.5 mg) as yellow oil.
