実験手順

To a solution of indole (3.00 g, 25.6 mmol) and methyl thioglycolate (2.40 mL, 25.6 mmol) in methanol:water (80 mL:20 mL) was added iodine (6.50 g, 25.6 mmol) and potassium iodide (4.25 g, 25.6 mmol). The reaction mixture was stirred at ambient temperature for 60 hours. Methanol was removed in vacuo and the aqueous layer diluted with a saturated solution of sodium bicarbonate and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, evaporated in vacuo and the resulting residue was purified on a silica gel column (0-100% ethyl acetate:hexanes over 33 min) to afford the desired product. LCMS>99% at 254 nm, RT=1.29 min, m/z=222 (M+1).
