YieldReaction ConditionsOperation in experiment
73% With potassium carbonate In N,N-dimethyl-formamide at 110℃; for 2h; 2 Synthesis of 4,6-di(9H-carbazol-9-yl)isophthalonitrile (Ref. 1). A mixture of carbazole (0406) (0.50 g, 3.05 mmol), 4,6-difluoroisophthalonitrile (1.53 g, 9.14 mmol), and potassium carbonate (1.69 g, 12.2 mmol) in 10 mL of N, A -di methylformami de (DMF) was stirred at 110 °C under ambient atmosphere for 2 h. The reaction mixture was poured into MeOH to afford yellow precipitation. After filtration, the resulting solid was washed with MeOH to give a yellow cake. The mixture was purified on silica gel column chromatography using 5: 1 (v/v) chloroform/hexane as eluent to give yellowish green solid (1.02 g) in 73.0% yield. NMR (500 MHz, CDCb, d): 8.49 (s, 1H), 8.14 (d, J= 7.0 Hz, 4H), 7.97 (s, 1H), 7.49 (t, J= 8.0 Hz, 4H), 7.40-7.36 (m, 8H).
With sodium hydride In tetrahydrofuran
2.3 g Stage #1: 9H-carbazole With sodium hydride In tetrahydrofuran; paraffin oil for 0.5h; Stage #2: 4,6-difluoro-1,3-benzenedicyanide In tetrahydrofuran; paraffin oil at 20℃; for 2h; 1.2 Synthesis of Intermediate 2 Containing 60% content in paraffin oilSodium hydride (0.9 g, 24.3 mmol) was washed with normal nucleic acid,A solution of carbazole (3.1 g, 18.2 mmol) in THF (tetrahydrofuran) at a concentration of 1 M is placed in sodium hydride.After stirring for 30 minutes, once all of the sodium hydride is dissolved, slowly add Intermediate 1 (1.0 g, 6.1 mmol) to a solution of 1 M in THF.After stirring at room temperature for 2 hours,The reaction is terminated by pouring methanol or distilled water.The reaction product was extracted with MC and subjected to column chromatography using a mixed solvent of chloroform / hexane to obtain 2.3 g of Intermediate 2.
