17 cm3 of a 7N solution of hydrogen chloride in dioxane is added at room temperature to a solution of 3.35 g of (3aRS,4RS,6SR,7aSR)-6-hydroxymethyl-4-(2-fluorophenyl)-2-tert-butyloxycarbonylperhydroisoindol-4-ol in 35 cm3 of dioxane. The reaction mixture is stirred at this temperature for 2 hours, then concentrated to dryness under reduced pressure (2.7 kPa). Trituration in diisopropyl ether gives 2.77 g of (3aRS,4RS,6SR,7aSR)-6-hydroxymethyl-4-(]2-fluorophenyl)perhydroisoindol-4-ol in the form of a thick white foam.
