A solution of 100 g (0.275 mol) of the levorotatory enantiomer of methyl (3aRS,4RS,7aSR)-2-benzyl-4-phenyl-7-oxoperhydroisoindole-3a-carboxylate and of 50 g (1 mol) of hydrazine hydrate in 750 cm3 of ethanol is brought to reflux for one and a half hours. After concentrating the ethanol under reduced pressure, the residue is taken up in 400 cm3 of dichloromethane and the organic phase is washed with distilled water and then with a saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated under reduced pressure. 100 g (960%) of the levorotatory enantiomer of methyl (3aRS,4SR,7aRS)-2-benzyl-7-hydrazono-4-phenylperhydroisoindole-3a-carboxylate are thus obtained in the form of a yellow oil used as is in the following stage.
