실험 절차

To a solution (10 ml) of ethyl 6-amino-6-(2-naphthyl)hexanoate (1.0 g) and 4-methylbenzenesulfonyl chloride (0.73 g) in THF was added triethylamine (0.39 g) dropwise and the mixture was stirred at room temperature for 2 hours. The reaction mixture was then diluted with water and extracted with ethyl acetate. The extract was dried and concentrated and the crude residue was recrystallized from ethyl acetate-hexane to provide the title compound (1.3 g).
