실험 절차

(3aRS,7aRS)-2-benzyl-7,7-diphenyl-4-perhydroisoindolone (150 g), methanol (1,500 cc) and 1N hydrochloric acid (450 cc) are added to 10% palladiumon-charcoal (15 g); the reaction mixture is hydrogenated, with stirring, at ambient temperature and under atmospheric pressure. After a reaction time of 5 hours, the theoretical volume of hydrogen has been absorbed; the reaction mixture is filtered and the filtrate is then concentrated to dryness under reduced pressure (2.7 kPa); the residue is crystallized from ethanol (200 cc); the crystals obtained are drained, washed with ethanol (50 cc) and dried. (3aRS,7aRS)-7,7-diphenyl-4-perhydroisoindolone hydrochloride (110 g) melting at 270° C. with decomposition is obtained.
