Embodiment A
[0046] (A1) Preparation of intermediate C1
[0047]
[0048] To 9-aminoanthracene ( 35.3 g, 183 mmol) and bromobenzene (59.9 g, 384 mmol) in degassed toluene (500 mL), and the mixture was heated at reflux for 2 hours. The reaction mixture was cooled to room temperature, diluted with toluene and filtered through celite. The filtrate was diluted with water and extracted with toluene, and the combined organic phases were evaporated under vacuum. The residue was filtered through silica gel (heptane / dichloromethane) and crystallized from isopropanol. The resulting solid (46.2 g, 134 mmol) and NBS (28.6, 161 mmol) were dissolved in a mixed solution of DMF and chloroform (1:3, 60 mL), stirred at room temperature for 6 hours, added water and extracted with dichloromethane, and dried the organic phase. Concentration and crystallization from isopropanol gave intermediate C1 (45.3 g, 80% of theory).

Embodiment A3
[0063] Example A3: Mass Spectrum m / z: 413.35 (calculated: 413.31). Theoretical element content (%)C 24 h 17 N 2 Br: C, 69.74; H, 4.15; N, 6.78; Br, 19.33 Measured element content (%): C, 69.78; H, 4.13; N, 6.78; Br, 19.35. The above results confirmed that the obtained product was the target product.
Embodiment A4
[0064] Example A4: Mass Spectrum m / z: 430.35 (calculated: 430.36). Theoretical element content (%)C 24 h 16 BrNS: C, 66.98; H, 3.75; Br, 18.57; N, 3.25; S, 7.45 Measured element content (%): C, 66.96; H, 3.73; Br, 18.51; The above results confirmed that the obtained product was the target product.
