실험 절차
0.072 g (0.151 mmol) tert-butyl-1-[3-(4-octylphenoxy)-2-oxopropyl]indole-3-carboxylate is dissolved in 10 ml absolute dichloromethane and mixed with 1.56 g (13.7 mmol) trifluoroacetic acid. Having stirred at room temperature for 1 hour, concentration to dryness is carried out on the rotary evaporator. Two dissolution steps in toluene and respective concentration on the rotary evaporator leave as the crude product a reddish solid which is recrystallized from petroleum ether/ethyl acetate (67:33) and yields the product as a white solid.
