Procedure

(3aRS,7aRS)-7,7-bis-(3-chlorophenyl)-2-vinyloxycarbonyl-4-perhydroisoindolone (1.5 g) is treated with a 6N solution (7.4 cc) of hydrochloric acid in dioxane for 2 hours at 25° C. The solution is concentrated to dryness under reduced pressure (2.7 kPa) and the residue is heated for 1 hour in solution in ethanol at 60° C. and then stirred for 6 hours at 25° C. The solution is concentrated to dryness under reduced pressure (2.7 kPa) and the meringue obtained is solidified in isopropyl ether. The precipitate is drained and washed with isopropyl ether and then dried to give 7,7-bis-(3-chlorophenyl)-4-perhydroisoindolone hydrochloride (1 g).
