실험 절차

2-Methyl-2,3-dihydro-benzoisothiazole (VI) (Hoffmann, R. W.; Goldman, S. Chem. Ber. 111, 1978, 2716-2725) (75 mg, 0.50 mmol) was dissolved in THF (1 mL) and added to indole (V) (140 mg, 0.60 mmol) under Ar. Tricloroacetic acid (90 mg, 0.55 mmol) was added and the reaction mixture was stirred at room temperature for 16 hours. 2 mL 1N NaOH (aq) was added. Extraction with ethyl acetate (2×10 mL) and purification by flash chromatography on silica gel (eluent: ethyl acetate then ethyl acetate/methanol/triethylamine) gave 88 mg [2-(1H-Indol-3-ylsulfanyl)benzyl]methyl amine (67% yield).
