실험 절차

(3aRS,7aRS)-7,7-diphenyl-2-vinyloxycarbonyl-4-perhydroisoindolone (177 g) is treated with a 5.7N solution (1,000 cc) of hydrochloric acid in dry dioxane for 30 minutes at 20° C. The solution is concentrated to dryness under reduced pressure (2.7 kPa) and the residue is taken up in ethanol (500 cc) and the reaction mixture is stirred at 60° C. for 30 minutes and then cooled to +5° C. The crystals obtained are drained, washed with ethanol (50 cc) and dried. (3aRS,7aRS)-7,7-diphenyl-4-perhydroisoindolone hydrochloride (130 g) melting at 270° C. is obtained.
