92% With potassium carbonate;palladium diacetate; tris-(o-tolyl)phosphine; In ethanol; water; toluene; at 90℃; for 4.5h;Inert atmosphere; [Example 5] This example will give descriptions of a method of synthesizing 2-[4-(dibenzofuran-4-yl)phenyl]-1-phenyl-1H-benzimidazole (abbreviation: DBFBIm-II) represented by the following Structural formula (130). [Show Image] [Synthesis of 2-[4-(dibenzofuran-4-yl)phenyl]-1-phenyl-1H-benzimidazole (abbreviation: DBFBIm-II)] The synthesis scheme of 2-[4-(dibenzofuran-4-yl)phenyl]-1-phenyl-1H-benzimidazole (abbreviation: DBFBIm-II) is illustrated in (B-5). [Show Image] In a 100-mL three-neck flask, a mixture of 1.7 g (5.0 mmol) of <strong>[2620-76-0]2-(4-bromophenyl)-1-phenyl-1H-benzimidazole</strong>, 1.0 g (5.0 mmol) of dibenzofuran-4-boronic acid, 22 mg (0.1 mmol) of palladium(II) acetate, 60 mg (0.2 mmol) of tri(ortho-tolyl)phosphine, 30 mL of toluene, 3 mL of ethanol, and 7.5 mL of a 2 mol/L aqueous solution of potassium carbonate was stirred to be degassed under reduced pressure. Then, the mixture was heated and stirred at 90 C for 4.5 hours under a nitrogen stream. After a predetermined time, 50 mL of toluene was added to this mixture solution, and the organic layer of the resulting suspension was suction filtered through Celite (produced by Wako Pure Chemical Industries, Ltd., Catalog No. 531-16855). The resulting filtrate was concentrated, followed by purification using silica gel column chromatography. The chromatography was carried out using a mixed solvent of toluene and ethyl acetate in a ratio of 19 to 1 as a developing solvent. The obtained fractions were concentrated, and hexane was added to the mixture, followed by irradiation with ultrasonic waves. The precipitated solid was collected by suction filtration. Thus, 2.0 g of a white powder was obtained in 92% yield, which was the substance to be produced. The Rf values of the produced substance and <strong>[2620-76-0]2-(4-bromophenyl)-1-phenyl-1H-benzimidazole</strong> were respectively 0.10 and 0.22, which were found by silica gel thin layer chromatography (TLC) (with a developing solvent containing ethyl acetate to hexane in a ratio of 1 to 10). A nuclear magnetic resonance (NMR) method identified this compound as 2-[4-(dibenzofuran-4-yl)phenyl]-1-phenyl-1H-benzimidazole (abbreviation: DBFBIm-II), which was the substance to be produced. 1H NMR data of the obtained substance are as follows: 1H NMR (CDCl3, 300 MHz): δ (ppm) = 7.27-7.63 (m, 13H), 7.74-7.78 (m, 2H), 7.89-8.00 (m, 5H). FIGS. 21A and 21B illustrate the 1H NMR charts. Note that FIG. 21B is a chart showing an enlarged part of FIG. 21 A in the range of 7.0 ppm to 8.5 ppm. Further, FIG. 22A shows an absorption spectrum of a toluene solution of DBFBIm-II, and FIG. 22B shows an emission spectrum thereof. FIG. 23A shows an absorption spectrum of a thin film of DBFBIm-II, and FIG. 23B shows an emission spectrum thereof. The absorption spectrum was measured using an ultraviolet-visible spectrophotometer (V-550, produced by JASCO Corporation). The measurements were performed with samples prepared in such a manner that the solution was put in a quartz cell while the thin film was obtained by evaporation onto a quartz substrate. The absorption spectrum of the solution was obtained by subtracting the absorption spectra of quartz and toluene from those of quartz and the solution, and the absorption spectrum of the thin film was obtained by subtracting the absorption spectrum of a quartz substrate from those of the quartz substrate and the thin film. In FIGS. 22A and 22B and FIGS. 23A and 23B, the horizontal axis represents wavelength (nm) and the vertical axis represents intensity (arbitrary unit). In the case of the toluene solution, an absorption peak was observed at around 323 nm, and emission wavelength peaks were 365 nm, 385 nm and 405 nm (excitation wavelength: 329 nm). In the case of the thin film, absorption peaks were observed at around 300 nm and 324 nm, and an emission wavelength peak was 405 nm (excitation wavelength: 330 nm).
