The powder was identified as compound (6) through an NMR spectrum (see FIG. 4) and an FD-MS (yield: 89%). The NMR spectrum was obtained under the same conditions as employed in Synthesis Example 1. |

After the completion of the reaction, the resultant solution was passed through a silicagel short column, and after concentrating under a reduced pressure, a precipitated crystal was separated by filtration. The crystal was washed with the use of 50 milliliter of toluene and 100 milliliter of methanol, and as a result, 4.5 g of pale yellow powder was obtained. The pale yellow powder was identified as a following Compound (5) from the result of 1H-NMR spectrum (refer to FIG. 6) and FD-MS measurement (the yield: 98 %). It was recognized that the peak absorption wavelength of the Compound (5) was 429 nanometers and the peak fluorescent wave length was 463 nanometers (toluene solution). |

97% | With sodium t-butanolate;tri-tert-butyl phosphine; bis(dibenzylideneacetone)-palladium(0); In hexane; xylene; at 130℃; for 1.5h; | Step 1: Synthesis of 3,3'-dimethyl-4"-phenyl-triphenylamine] [0751]A synthetic scheme of 3,3'-dimethyl-4"-phenyl-triphenylamine in Step 1 is shown in the following (T-I). [0752][0753]In a 100-mL three-neck flask, 5.8 g (25 mmol) of 4-bromobiphenyl, 4.9 g (25 mmol) of m,m'-Ditolylamine, 3.0 (30 mmol) of sodium terf-butoxide, and 140 mg (0.25 mmol) of bis(dibenzylideneacetone)palladium(0) were put, and the atmosphere of the flask was substituted by nitrogen. Then, 50 mL of dehydrated xylene was added to this mixture. This mixture was deaerated while being stirred under low pressure. After the deaeration, 1.0 mL(0.5 mmol) of tri(terf-butyl)phosphine (10 wt% hexane solution) was added thereto. This mixture was stirred under a nitrogen atmosphere at 130 0C for 1.5 hours to be reacted. [0754]After the reaction, 80 mL of toluene and 420 mL of hexane were added to this reaction mixture, and this suspension was filtrated through Florisil, silica gel, and then Celite. The obtained filtrate was washed with water. Then, magnesium sulfate was added to remove moisture. This suspension was filtrated through Florisil and then Celite to obtain filtrate. The obtained filtrate was concentrated, and methanol was added thereto. The mixture was irradiated with supersonic and then recrystallized to obtain 8.5 g of an objective white powder at a yield of 97 %. [0755] A compound which was obtained through the above Step 1 was measured by a nuclear magnetic resonance method (1H NMR). 1H NMR (CDCl3, 300 MHz): delta (ppm) = 2.28 (s, 6H), 6.85 (d, J = 6.9, 2H), 6.91-6.95 (m, 4H), 7.09-7.18 (m, 4H), 7.29 (t, J = <n="251"/>7.5, IH), 7.38-7.48 (m, 4H), 7.56-7.59 (m, 2H). |

After the mixture has been cooled to 60 C., 500 ml of water are added, the organic phase is separated off, filtered through silica gel, evaporated virtually to dryness at 80 C. in vacuo, and 300 ml of ethanol are then added. After cooling, the solid is filtered off with suction. Recrystallisation five times from dioxane (about 8 ml/g); sublimation (p=5*10-5 mbar, T=280 C.). Yield: 11.9 g (28 mmol), 56.1%, purity 99.9% (HPLC). |

Step a: The synthesis is carried out analogously to Example 1, with the difference that 104.1 g (527 mmol) of <strong>[626-13-1]di(3-methylphenyl)amine</strong> are employed instead of the di-p-tolylamine and 153.1 g (211 mmol) of 2,7-diiodo-2',7'-dibromo-9,9'-spirobifluorene are employed instead of the dibromospirobifluorene. After crystallisation from dioxane and sublimation, 134.5 g (190 mmol, 90%) of N,N,N',N'-tetrakis(3-methylphenyl)-2',7'-dibromo-9,9'-spirobifluorene-2,7-diamine are obtained as a colourless solid. |
