実験手順

To a 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and reflux condenser was charged with 1,4-dioxane (15 mL), 3,5-dibromoisonicotinaldehyde (200 mg, 0.76 mmol), 8-thia-4,5-diazatricyclo[7.4.0.02,7]trideca-1(9),2(7),3-trien-6-one 191d (160 mg, 0.76 mmol), and cesium carbonate (176 mg, 1.5 mmol). Cuprous iodide CuI (100 mg, 0.76 mmol) and 4,7-dimethoxy-1,10-phenanthroline (127 mg, 0.52 mmol) were added, and the reaction mixture was heated at 100° C. for 5 h. After this time the reaction was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was purified on flash column eluting with EtOAC/PE (1:2) to afford 116a (80 mg, 30%). MS: [M+H]+ 390.
