Reaktionsschritte

9,10-Bis(3-methylanilino)phenanthrene was mixed in an amount of 6.6 g (17.0 mmol) with 14.8 g (68.0 mmol) of m-iodotoluene, 3.82 g (68 mmol) of potassium hydroxide, 0.98 g (6.8 mmol) of copper-(I) bromide, 2.52 g (6.8 mmol) of ethyltriphenylphosphonium bromide, and 10 mL of terpinolene. This mixture was reacted at 115-125° C. for 2 hours in a nitrogen stream. After the reaction, the reaction solvent was distilled off by vacuum concentration. To the residue were added 5 mL of toluene, 67 mL of ethyl acetate, and 22 mL of water. The resultant mixture was subjected to liquid separation. To the organic layer was added 71 mL of methanol. The resultant solution was cooled for crystallization. Thus, the target compound (I-22) was obtained as light-yellow crude crystals in an amount of 9.0 g (yield, 93.0%). The target compound obtained had a melting point of 223-224° C. and a content as determined by HPLC of 99.6% (HPLC conditions: column, YMC-A-312; eluent, methanol/tetrahydrofuran (V/V=99/1); detection UV, 254 nm; flow rate, 1.0 mL/min).
