実験手順

Into a 8-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 6-[bis(4-chlorophenyl)methyl]-4-bromoquinolin-2-ol (150 mg, 0.33 mmol, 1.00 equip), 1,4-dioxane (3 mL), cyclohexanamine (48.5 mg, 0.49 mmol, 1.50 equip), Pd2(dba)3 (30 mg, 0.03 mmol, 0.10 equip), dppf (63.4 mg, 0.11 mmol, 0.35 equip), and Cs2CO3 (266 mg, 0.82 mmol, 2.50 equip). The resulting solution was stirred overnight at 100° C. The reaction was then quenched by the addition of water (100 mL). The resulting solution was extracted with ethyl acetate (3×50 mL) and the organic layers combined and dried over anhydrous sodium sulfate. The solids were filtered out. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (20:1). The resulting residue was recrystallized from ethyl acetate:petroleum ether in the ratio of 1:10 to yield 6-(bis(4-chlorophenyl)methyl)-4-(cyclohexylamino)quinolin-2(1H)-one as an off-white solid.
