실험 절차
Butylamine (15 ml) in toluene (40 ml) was cooled to −78° C. and a 2.5M solution of butyllithium in hexane (12.91 ml, 31.5 mmol) was added dropwise. After half an hour, ethyl 3,3-dimethylindoline-2(R/S)-carboxylate (4.600 g, 21 mmol) was added to the solution and this mixture was stirred under nitrogen for three hours. The mixture was then poured into a water/ice mixture (50 ml) and extracted with ethyl acetate; the extracts were dried over magnesium sulphate and the solvent was removed to give a brown oil. This was purified by chromatography on a column of silica gel, using a 7/3 petroleum ether/ethyl acetate mixture as eluent in order to give a yellow solid.
