Procedure

N,N'-Carbonyldiimidazole (1.13 g) is added to a solution of 2-(3-thienyl)acetic acid (0.99 g) in dry dichloromethane (30 cc), cooled to +5° C. The mixture is stirred for 15 minutes at +5° C. and a solution of (3aRS,7aRS)-7,7-diphenyl-4-perhydroisoindolone hydrochloride (2.24 g) and triethylamine (1.96 cc) in dichloromethane (20 cc) is then added. The reaction mixture is stirred for 16 hours at 20° C., then washed with distilled water (3×50 cc), dried over magnesium sulphate and filtered and the filtrate is concentrated to dryness under reduced pressure (2.7 kPa). The residue is recrystallized from a mixture of acetonitrile (30 cc) and isopropyl ether (40 cc). The crystals are drained, washed with isopropyl ether and dried. (3aRS,7aRS)-7,7-diphenyl-2-[2-(3-thienyl)acetyl]-4-perhydroisoindolone (2.2 g) melting at 224° C. is obtained.
