実験手順

(3aRS,7aRS)-7,7-bis-(3-fluorophenyl)-2-vinyloxycarbonyl-4-perhydroisoindolone (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 is taken up in ethanol (500 cc). The solution is heated at 60° C. for 6 hours and stirred for 16 hours at 25° C. and then concentrated to half its volume under reduced pressure (2.7 kPa) and the crystals formed are drained and washed with isopropyl ether and then dried. 7,7-Bis(3-Fluorophenyl)-4-perhydroisoindolone hydrochloride (48.7 g) is obtained. m.p.=264° C.
