Reaction Steps

(±)-(3aR*,7aS*)-7a-(2-Fluorophenyl)-5-methoxyoctahydrobenz[c]isoxazole obtained in Preparation Example 59-(5) (5.60 g) was dissolved in acetic acid (128 mL). Then, zinc powder (14.1 g) was added and the mixture was stirred at room temperature for eight hours. The solid was removed by filtration through celite, and then the celite was washed with ethyl acetate. The resulting filtrate was concentrated under reduced pressure. The residue was dissolved in ethyl acetate. Then, a saturated sodium bicarbonate solution was added, followed by vigorous stirring. The organic layer was separated and then the aqueous layer was extracted again with ethyl acetate twice. The combined organic layers were dried over anhydrous magnesium sulfate. The solid was removed by filtration and the filtrate was concentrated under reduced pressure to obtain the title compound (5.49 g).
