실험 절차
A 700 mg portion of ethyl 5-tert-butyl-4-formyl-2-methyl-1-(2-phenylethyl)-1H-pyrrole-3-carboxylate was dissolved in 21 ml of trifluoroacetic acid, mixed with 3.3 ml of triethylsilane at 0° C. and stirred for 2 hours while rising the temperature from 0° C. to room temperature. The solvent was evaporated under a reduced pressure, azeotropy with toluene was carried out, and then the residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:50-1:40-1:30) to obtain 652 mg of ethyl 5-tert-butyl-2,4-dimethyl-1-(2-phenylethyl)-1H-pyrrole-3-carboxylate as a colorless oil.
