Participants

Reaction Steps

6a-Methyl-5,6,6a,7,8,9-hexahydro-4H-2-phenalenylamine (0.100 g) was dissolved in pyridine (5 ml) and anhydrous benzene (2 ml), the solution was added with 4-chlorosulfonylbenzoic acid (0.115 g) and 4-dimethylaminopyridine (one pellet), and the mixture was stirred overnight at room temperature. The reaction mixture was added with 2 N aqueous hydrochloric acid and thereby made acidic, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. The organic layer was concentrated under reduced pressure, and the resulting residue was recrystallized from ethyl acetate-n-hexane to obtain the title compound (0.110 g, yield: 57%) as colorless needles (melting point: 215-217° C.).
