실험 절차

3-ethoxycarbonyl-5-methyl-4-(naphthalen-1-yl)-1H-pyrrole 4.3 g(18.9 mmol) of 3-(naphthalen-1-yl)-acrylic acid ethylester prepared in Preparation 6-1) and 3.95 g(18.9 mmol) of α-methyltosylmethylisocyanide disclosed in A. M. van Leusen, et al., Tetrahedron Letter, 1975, 40, 3487 were dissolved in 100 ml of tetrahydrofuran. 2.55 g(22.7 mmol) of potassium t-butoxide dissolved in 100 ml of tetrahydrofuran was slowly added thereto, which was then refluxed for 30 minutes. To the reaction solution was added 100 ml of water to stop the reaction and the solvent was removed under reduced pressure. The residue was extracted with diethylether, washed with saturated sodium chloride solution and dried over magnesium sulfate. The solvent was removed under reduced pressure and the residue was subjected to silica gel column chromatography using a solvent mixture of ethyl acetate/n-hexane(1/3, v/v) as an eluent to give 3.50 g(12.5 mmol, Yield 66%) of the title compound.
