実験手順

In a tube were added successively (2-Iodo-5-methanesulfonyl-phenyl)-[4-(4-trifluoromethyl-phenyl)-piperazin-1-yl]-methanone (compound CK, 0.1 g, 0.19 mmol), 1,2,4-triazole (11 mg, 0.155 mmol), potassium phosphate (71 mg, 0.326 mmol), CuI (7 mg, 0.037 mmol), (1R,2R)-diaminomethylcyclohexane (2.3 mg, 0.015 mmol) and DMF (1 ml). The mixture was heated under argon at 120° C. for 24 hours. The reaction mixture was cooled to room temperature and quenched with water/dichloromethane. The aqueous layer was extracted twice with dichloromethane. The organic layers were combined, dried over Na2SO4, filtered and the solvent was removed in vacuo. The crude oil was chromatographed over silicagel: eluent: heptane/ethylacetate: 0-100% to provide the title compound as a light grey solid (5 mg, 6%), MS (m/e): 480.4 (M+H, 100%)
