Versuchsvorschrift

A solution of 5,6,6a,7,8,9-hexahydro-4H-2-phenalenylamine (0.260 g) in anhydrous benzene (10 ml) and pyridine (3 ml) was added with monomethyl terephthalate chloride (0.304 g), and the mixture was stirred at room temperature for 3 hours. The reaction mixture was added with 2 N aqueous hydrochloric acid and thereby made acidic, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water, 10% aqueous sodium carbonate, water and saturated brine, and then dried over anhydrous sodium sulfate. The organic layer was concentrated under reduced pressure, and the resulting residue was recrystallized from chloroform-n-hexane to obtain the title compound (0.460 g, yield: 95%) as colorless needles (melting point: 217-218° C.).
