반응 단계
50.0 g (0.19 mol) of 9-p-tolylcarbazole (4c), 100.0 g (1.37 mol) of DMF, 51.8 g (0.38 mol) of zinc chloride, 174.8 g (1.14 mol) of phosphorus oxychloride and 500 g of toluene were allowed to react and after treated in the same manner as with Example 1 (1), and treated by silica gel column chromatography (eluent: toluene/ethyl acetate=9/1 by volume) to obtain 16.65 g of crude crystals. These crystals were recrystallized from toluene to obtain 14.33 g of 3,6-diformyl-9-p-tolylcarbazole.
