実験手順

To a slurry of 0.45 g (9.4 mmol) sodium hydride (50% dispersion in mineral oil) in 40 mL anhydrous THF was added 1.90 g 5-allyloxyindole. The slurry was stirred at room temperature for 15 min upon which time 1.14 mL (9 mmol) benzene sulfonyl chloride was added dropwise. The reaction was stirred at room temperature over three nights and then poured into water and extracted with ethyl acetate. The organic extracts were dried over MgSO4 and concentrated. The product solidified upon concentration and the crude material was triturated with diethyl ether to afford 1.36 g of 5-allyloxy-1-benzenesulfonyl-1H-indole as a light brown solid.
