실험 절차

To a solution of hexahydropyrrolo[1,2-a]pyrazin-8a(6H)-ylmethanol (D67, 35 mg) in methyl sulfoxide (1.5 mL), 2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-chloro-4-(4-fluoro-2-methylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide [WO 2005/002577] (60 mg) and potassium carbonate (63 mg) were added. The resulting mixture was heated at 150° C. for 24 hours. The mixture was allowed to cool down to r.t and further D67 (17 mg) and potassium carbonate (15 mg) were added. The resulting mixture was heated at 150° C. for further 8 hours and then it was allowed to cool to r.t. and diluted with water (2 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 twice by flash chromatography (first purification: EtOAc/Cycl from 80/20 to 100:0 then DCM/MeOH 95:5. Second purification: DCM/MeOH 98:2) to give the desired compound (7.7 mg) as yellow foam.
