Participants

Reaction Steps

A mixture of 2-butyrylfluorene (11.3 g.), powdered potassium hydroxide (4.16 g.) and 100% hydrazine hydrate (9 ml.) in ethylene glycol (104 ml.) was refluxed for 1 hour with stirring. The mixture was then slowly distilled until the boiling-point reached 185° and then heated to reflux for 3 hours. The cooled mixture was treated with water (ca. 300 ml.) and the product was isolated with ether in the usual manner. Recrystallisation from methanol gave 2-butylfluorene, m.p. 65°-66.5°.
