Reaction Steps

Into a three-neck flask, 10 g (3.6×10−2 mol) of 2-bromo-5-methoxyterephthalic acid prepared in the above step (2), 12.04 g (7×10−2 mmol, 2 eq) of carbazole, 12.94 g (9.4×10−2 mmol, 1.3 eq) of K2CO3 and 0.3 g (3% w/w) of Cu were introduced and reacted in the presence of 300 ml of DMF for 48 hours, then cooled to room temeparature. The used solvent was distilled off under reduced pressure and the aqueous solution was washed with water and diethyl ether several times. To the aqueous solution so obtained, 5 N HCl was slowly added to produce yellow precipitates, which were then recrystallized with CHCl3. Yield: 50% (6.5 g); m.p.: 298° C.
