Reaction Conditions

Reaction Steps

Carbazole (23.66 g, 0.16 mol), potassium hydroxide (14.45 g. 0.226 mol), water (30 g) and line (100 g) were added into a 500 ml four neck flask equipped with Dean-stark apparatus, and refluxed. Water (about 30 g) was separated, and the reaction mixture was cooled to 90 to 100° C. Hexyl bromide (33 g, 0.2 mol) was added dropwise thereto over about 25 minutes, and then reflux was carried out for 1 hour. 9-hexylcarbazole was obtained in a 95% yield.
