実験手順

A solution of 0.43 g of 2-(3-indolyl)-2-oxoacetyl chloride in 20 cm3 of dry dichloromethane and then a solution of 0.6 cm3 of triethylamine in 5 cm3 of dry dichloromethane are added in succession to a suspension of 0.96 g of (3aS,4S,7aS)-7,7-diphenyl-4-(2-methoxyphenyl)perhydroisoindol-4-ol hydrochloride in 25 cm3 of dry dichloromethane at room temperature, while stirring. The reaction mixture is stirred at this temperature for 24 hours, subsequently diluted with 200 cm3 of dichloromethane, washed with 100 cm3 of an aqueous 1N solution of sodium hydroxide and with 50 cm3 of an aqueous saturated solution of sodium chloride, and is dried over magnesium sulphate and concentrated to dryness under reduced pressure (2.7 kPa). The residue is chromatographed on a Merck silica gel column (particle size 0.04-0.06 mm, diameter 2.5 cm, height 1 cm) by eluting under a pressure of 0.4 bar of nitrogen with a mixture of 1,2-dichloroethane and methanol (70/30 by volume) and collecting fractions of 15 cm3. Fractions 2 to 9 are combined and concentrated to dryness under reduced pressure (2.7 kPa). 1.15 g of (3aS,4S,7aS)-7,7-diphenyl-2-[2-oxo-2-(3-indolyl)acetyl]-4-(2-methoxyphenyl)perhydroisoindol-4-ol are obtained in the form of an orange foam.
