実験手順

To an oven-dried 50 mL round-bottomed flask were added 2-chloro-4-(4-trifluoromethyl-phenyl)-pyridine (138 mg, 0.54 mmol) and 3-aminoquinoline (Aldrich Chemical Company) (93 mg, 0.64 mmol), followed by anhydrous toluene (45 mL). Nitrogen was bubbled through the above solution via a needle for 1 h. Then palladium acetate (Aldrich Chemical Company) (18 mg, 0.08 mmol) and BINAP (Aldrich Chemical Company) (50 mg, 0.08 mmol) were added to the reaction in one portion, followed by sodium tert-butoxide (Aldrich Chemical Company) (145 mg, 1.5 mmol). The reaction mixture was heated at 90° C. overnight. After cooling to room temperature, the reaction mixture was taken up to ether, and washed with brine. The aqueous layer was extracted with ether (2×) and the combined ether layer was dried over Na2SO4 and concentrated. The residue was purified on a Biotage 40 S column (2.5:1 hexane:EtOAc) to give the title compound as an off-white solid. MS (ESI, pos. ion) m/z: 366 (M+1). Mp: 207.4-207.5° C.
