Procedure

4.2 cm3 of triethylamine and then 2.4 g of (2-methoxyphenyl)acetic acid chloride in 50 cm3 of dichloromethane are added to a solution of 4.5 g of (3aRS,4RS,5RS,7aRS)-7,7-diphenyl-4-(2-methoxyphenyl)perhydroisoindole-4,5-diol hydrochloride in 100 cm3 of dichloromethane, cooled to 0° C. The reaction mixture is stirred at room temperature for 90 minutes; it is washed with twice 10 cm3 of water, and is dried over magnesium sulphate and concentrated to dryness under reduced pressure (2.7 kPa). The solid which has crystallized is taken up in. 100 cm3 of diisopropyl ether and then filtered off and washed with 50 cm3 of a saturated solution of sodium bicarbonate and then 50 cm3 of diisopropyl ether. 4.35 g of (3aRS,4RS,5RS,7aRS)-7,7-diphenyl-4-(2-methoxyphenyl)-2-(2-methoxyphenyl)- acetylperhydroisoindole-4,5-diol are obtained in the form of a light beige solid which melts at 278° C.
