86% | With tris-(dibenzylideneacetone)dipalladium(0); sodium t-butanolate; XPhos; In toluene; at 100 - 110℃; for 2h;Inert atmosphere; | (1) To mechanical agitation, thermometer, After replacing the three-port reaction flask in the condenser with nitrogen, Add intermediate 24a (100mmol) in sequence, Raw material 24b (95mmol), 300ml toluene, heated to reflux for 0.5h, Cool down to 70 - 80 C, Slowly add sodium tert-butoxide (150mmol), Pd2 (dba) 3 (0.25mmol), xphos (0.5mmol), After the system is stable, it is heated to 100 - 110 C for 2 hours. Reduce the temperature to 25 - 30 C, add 200ml of water, stir and separate with 100ml of toluene, and extract the aqueous phase once with 200ml of toluene. Separate the liquid, combine the organic phase, add 7g of anhydrous sodium sulfate to the organic phase, stir and dry, filter The organic phase is concentrated (-0.08-0.09MPa, 55-60 C ) so that Recrystallize with 60ml toluene, filter, 82 mmol of intermediate 24c was obtained with a yield of 86%. |
70% | With tri-tert-butyl phosphine; palladium diacetate; sodium t-butanolate; In toluene; at 100℃; for 72h;Inert atmosphere; Sealed tube; | An oven-dried pressure tube was cooled under nitrogen and charged with 9-bromanthracene (0.5 g, 1.9 mmol), distilled aniline (0.26 mL, 2.9 mmol), NaOtBu (0.44 g, 3.8 mmol), Pd(OAc)2 (22 mg, 5 mol%) and P(tBu)3 (23 uL, 0.1 mmol). To this was added dry toluene (10 mL). The pressure tube was sealed under nitrogen and stirred at 100 C for 72 h. After 72 h, the pressure tube was cooled to rt and toluene was removed in vacuo. Subsequently, the reaction was quenched with water and the organic contents were extracted with chloroform. The combined extract was dried over anhyd Na2SO4 and filtered. The solvent was removed in vacuo and the crude product was subjected to silica gel column chromatography using CHCl3/pet.ether (5:95) as an eluent to yield pure 9-(N-phenylamino)anthracene as yellow crystalline solid (0.36 g, 70% yield); mp 145 C; IR (neat film) cm1 3392, 1601, 1499, 1421, 1355, 1307; 1H NMR (CDCl3, 500 MHz) d 5.99 (s,1H), 6.59 (d, J = 8.0 Hz, 2H), 6.78 (t, J = 6.8 Hz, 1H), 7.14(t, J = 7.4 Hz, 2H), 7.44-7.48 (m, 4H), 8.05 (d, J = 8.6 Hz,2H), 8.19 (d, J = 8.6 Hz, 2H), 8.41 (s, 1H); 13C NMR (CDCl3, 125 MHz) d 113.8, 118.4, 123.8, 125.3, 125.4, 125.8,128.7, 129.0, 129.2, 132.2, 132.4, 147.9; EI-MS+ m/z Calcdfor C20H15N 269.1204 [M+], found 269.1206. |

92% | With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In toluene; for 12h;Inert atmosphere; Reflux; | d. Preparation of Intermediate IInto a RBF (5000 mL) was added 9-bromoanthracene (100 g, 0.389 mol), 4-(Naphthalene-1-yl) Phenyl boronic acid (116 g, 0.469 mol), followed by the addition of toluene (3000 mL). The mixture was purged with N2 for 10 min. Then Na2CO3 (124 g, 1.167 mole) dissolved in the water (600 mL) was added. The mixture was continued to be purged with N2 for 10 min. A catalytic amount of Pd(PPh3)4 (2.3 g, 1.95 mmole) was added. The mixture was refluxed under N2 for 12 h. Cooled down the reaction mixture to 40 C., filtered, separated off water layer, and concentrate the organic phase to a final volume (150 ml) to obtain the solid of intermediate I (131 g, yield: 92%). C30H2O: El, MS m/z (%): 380 (100, M+). |

3.3g | With potassium phosphate; tetrakis(triphenylphosphine) palladium(0); for 8h;Inert atmosphere; Reflux; | Under the nitrogen atmosphere, triphenylen-2-ylboronic acid (5.6 g), 9-bromoanthracene (3.5 g), (Pd(PPh3)4) (0.5 g), potassium phosphate (5.8 g), and a mixture solvent of pseudo cumene, t-butyl alcohol, and water (48 ml) (pseudo cumene/t-butyl alcohol/water = 10/1/1 (volume ratio)) were added to a flask and then refluxed for 8 hours. After adding water, the precipitates were collected by suction filtration. The obtained solid was washed with water followed by methanol and purified by silica gel column chromatography (solvent: toluene). After re-crystallization with a mixture solution of toluene/ethyl acetate, 2-(anthracen-9-yl)triphenylene (3.3 g) was obtained as an eleventh intermediate compound.
