실험 절차

0,766 g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide is added to a solution, cooled to 10° C., of 1 g of (3aR,4S,7aR)-7,7-diphenyl-4-perhydroisoindolol, 0.97 g of 2-(3-dimethylaminopropoxy)phenylacetic acid and 0.05 g of 1-hydroxybenzotriazole in 50 cm3 of dichloromethane. The reaction mixture is stirred for 90 minutes 20° C. and then washed twice with 50 cm3 of water and with 50 cm3 of a saturated solution of sodium chloride. The organic phase is dried over magnesium sulphate and concentrated to dryness under reduced pressure (2.7 kPa). The residue is chromatographed on a silica gel column (particle size 0.2-0.063 mm, diameter 2.9 cm, height 23 cm), eluting under a nitrogen pressure of 0.7 bar with 1,2-dichloroethane and methanol mixtures (1 liter at 90/10 by volume and 1.5 liters at 70/30 by volume) and collecting fractions of 25 cm3. Fractions 10 to 84 are pooled and concentrated to dryness under reduced pressure (2.7 kPa) to give 1.1 g of (3aR,4S,7aR)-2-{[2-(3-dimethylaminopropoxy)phenyl]-acetyl}-7,7-diphenyl-4-perhydroisoindolol in the form of a cream-colored meringue.
