Water → 9-(4-Nitrophenyl)-9H-carbazole

Participants

Reaction Steps

A mixture of 334.4 (2 mol) of carbazole, 472.8 g of p-chloro-nitrobenzene (3 mol) and 691 g (5 mol) of anhydrous potassium carbonate were stirred in 1500 ml of dimethylacetamide for 13 h at reflex temperature. The reaction mixture was then poured into 7 of water and the precipitate separated by suction filtering. Said precipitate was stirred in 4 of water and neutralized with 1 N hydrochloric acid, whereupon the precipitate was filtered again. After drying the solid product was recrystallized from a mixture of tetrahydrofuran and methanol and the yellow product obtained was dried. Yield: 465 g. Melting point: 211° C.
