Reaction Steps

To carbazole (5.02 g) in DMSO (50 mL) is added 4-fluoroacetophenone (3.45 g) and K2CO3 (10.4 g), and the mixture is stirred at 135° C. overnight. The mixture is poured into water to afford a precipitate, which is isolated by filtration and washed with water. The crude product thus obtained is further purified by recrystallization from TBME (tert-butyl methyl ether), giving the product as a light brown solid. The structure is confirmed by the 1H-NMR spectrum (CDCl3). δ[ppm]: 2.71 (s, 3H), 7.32 (ddd, 2H), 7.41-7.50 (m, 4H), 7.72 (d, 2H), 8.15 (d, 2H), 8.21 (d, 2H).
