실험 절차

A suspension of 4-fluorophenylhydrazine hydrochloride (50 g) in water (500 ml) was treated with sodium hydroxide (12.3 g) in water (50 ml) and the resultant solution added to solution of cyclohexane-1,3-dione (97%, 35.6 g) in water (300 ml) over 2 h under nitrogen with stirring. After a further 30 min, the precipitate was filtered off, washed with water (50 ml), air dried for 1 h, and dried in vacuo over phosphorus pentoxide at 75° to give the title compound as a powder (65.3 g) m.p. 175°-176°.
