실험 절차
(3aRS,7aRS)-7,7-Bis(3-fluorophenyl)-2-vinyloxycarbonylperhydro-4-isoindolone (64.5 g) is treated with a 6N solution (330 cc) of hydrochloric acid in dioxane for 30 minutes at 25° C. The solution is concentrated to dryness under reduced pressure (2.7 kPa) and the residue taken up with ethanol (500 cc). The solution is heated to 60° C. for 6 hours and stirred for 16 hours at 25° C., then concentrated to one half under reduced pressure (2.7 kPa), and the crystals formed are drained and washed with isopropyl ether, then dried. 7,7-Bis(3-fluorophenyl)perhydro-4-isoindolone hydrochloride (48.7 g) is obtained. M.p. 264° C.
