実験手順
2.1 g (52.5 mmol) of NaH (60% in mineral oil) are dissolved in 500 ml of THF under a protective-gas atmosphere. 11.5 g (50 mmol) of 3-phenyl-4H-furo[3,4-b]indole and 11.5 g (52.5 mmol) of 15-crown-5 dissolved in 200 ml of THF are added. After 1 h at room temperature, a solution of 12.7 g (55 mmol) of 2-bromobenzenesulfonyl chloride in 250 ml of THF is added dropwise. The reaction mixture is stirred at room temperature for 18 h. After this time, the reaction mixture is poured onto ice and extracted three times with dichloromethane. The combined organic phases are dried over Na2SO4 and evaporated. The residue is extracted with hot toluene and recrystallised from toluene/n-heptane. The yield is 16 g (75%).
